[Kernel-packages] [Bug 1749420] Re: [regression] Colour banding and artefacts appear system-wide on an Asus Zenbook UX303LA with Intel HD 4400 graphics

[Kai-Heng Feng]

I guess we can also bisect to the exact bad commit and report it to i915
developers.

> If it's any help, this problem seems to have been introduced in kernel
4.8. I tested different kernels with UKUU. Kernels prior to 4.8 do not
have the colour banding issue.

Please find which v4.8-rc* release introduced this bug.

Title:
  [regression] Colour banding and artefacts appear system-wide on an
  Asus Zenbook UX303LA with Intel HD 4400 graphics

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  - Ubuntu 18.04 (with updates as of 14 Feb 2018).
  - Laptop: Asus Zenbook UX303
  - CPU: Intel i5 4210U
  - Graphics: Intel HD 4400

  Problem description: Colour artefacts and banding in all apps.
  Graphics, photos and videos display as though the colour range is
  improperly configured.

  See this photo of a 1080p video taken with a camera (poor quality, but
  illustrates the issue): https://ubuntucommunity.s3-us-
  
east-2.amazonaws.com/original/2X/c/c8f266715226953c6a77db6367ff9b7895784e35.jpg

  Look at the sky’s light colours. They display with smooth gradients on
  Ubuntu 16.04, but as the photo illustrates 18.04 seems to display the
  video with a smaller range of white colours. This is the most apparent
  with either very dark or very light colours. Even on window titlebars
  the banding is visible (displayed as lines with different shades of
  grey/black).

  Compared with a PrtSc shot of the same image:
  https://i.imgur.com/VkOSCaQ.png

  The artefacts are not present on PrtSc shots that are taken on Ubuntu
  18.04 but viewed on a different system (16.04 and Windows).

  Installing a previous kernel version fixes the issue completely. I
  used UKUU Update Utility to install kernel 4.4 (the same that I use in
  Ubuntu 16.04 without issues) and upon a reboot with 4.4 running on
  18.04 everything displayed smoothly. So this indicates that the system
  might be using a sub-optimal colour depth with the newer kernel?

Dear Joseph

Thanks for your suggestion. That seemed to work beautifully and my very
old computer seems happy again.

I am amazed that Ubuntu has such excellent help and support!

Thanks again

I'll back port the patch to v4.15 so Bionic (18.04) live image will have this

Bug description:
  Ubuntu 4.13.0-21.24-generic 4.13.13

  
  I have a Razer Blade Stealth 2016. The first Ubuntu I installed was Ubuntu 
17.04, which gave me this error after 2 weeks of usage. After that, I installed 
16.04 and used it for MONTHS without any problems, until it produced the same 
error this week. I think it has to do with the ubuntu updates, because I did 
one recently and one today, just before this problem. Could be a coincidence 
though.

  I notice the error when I try to save something on disk and it says me
  that the disk is in read-only mode:

  Rebooting the ubuntu will give me a black terminal where I can run
  fsck /dev/nvm30n1p2 (something like that) and it fill fix a lot of
  orphaned inodes. The majority of time it boots back to the Ubuntu
  working good, but some times it boots to a broken ubuntu (no images,
  lots of things broken). I have to reinstall ubuntu then.

  Every time I reinstall my Ubuntu, I have to try lots of times until it
  installs without an Input/Output error. When it installs, I can use it
  for some hours without having the problem, but if I run the software
  updates, it ALWAYS crashes and enters in read-only mode, specifically
  in the part that is installing kernel updates.

  I noticed that Ubuntu installs updates automatically when they're for
  security reasons. Could this be the reason my Ubuntu worked for months
  without the problem, but then an update was applied and it broke?

  I thought that this bug was happening:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184 and tried
  different nvme_core.default_ps_max_latency_us= combinations, all them
  gave errors. I just changed to 0 and I had no error while using ubuntu
  (however I didn't test for a long time) but I still had the error
  after trying to update my ubuntu.

  My Samsung 512gb SSD is:

  SAMSUNG MZVLW512HMJP-0, FW REV: CXY7501Q

  on a Razer Blade Stealth.

  I also asked this on ask ubuntu, without success:
  https://askubuntu.com/questions/998471/razer-blade-stealth-disk-
  corruption-fsck-needed-probably-samsung-ssd-bug-afte

  Please help me, as I need this computer to work on lots of things :c

[Kernel-packages] [Bug 1749818] Re: Call Trace messages in syslog with 4.4.0-116 kernel

[Rod Smith]

Every other system I've run through this round has shown the same
failure on this test. I suspect it's simply a very high false alarm
rate, as Jeff suggests, so I'm closing this out as "invalid."

  In doing regression testing of the 4.4.0-116 kernel with the server
  certification tools, the miscellanea/call-trace-check test failed on
  one system. (Maybe more, too; this was the first system to finish the
  tests.) This test simply looks for the string "Call Trace" in
  /var/log/syslog, and there are 44 such call traces. The system being
  tested was an Intel NUC DC53427HYE. The complete test results are
  available here:

Title:
  [regression] Colour banding and artefacts appear system-wide on an
  Asus Zenbook UX303LA with Intel HD 4400 graphics

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  - Ubuntu 18.04 (with updates as of 14 Feb 2018).
  - Laptop: Asus Zenbook UX303
  - CPU: Intel i5 4210U
  - Graphics: Intel HD 4400

  Problem description: Colour artefacts and banding in all apps.
  Graphics, photos and videos display as though the colour range is
  improperly configured.

  See this photo of a 1080p video taken with a camera (poor quality, but
  illustrates the issue): https://ubuntucommunity.s3-us-
  
east-2.amazonaws.com/original/2X/c/c8f266715226953c6a77db6367ff9b7895784e35.jpg

  Look at the sky’s light colours. They display with smooth gradients on
  Ubuntu 16.04, but as the photo illustrates 18.04 seems to display the
  video with a smaller range of white colours. This is the most apparent
  with either very dark or very light colours. Even on window titlebars
  the banding is visible (displayed as lines with different shades of
  grey/black).

  Compared with a PrtSc shot of the same image:
  https://i.imgur.com/VkOSCaQ.png

  The artefacts are not present on PrtSc shots that are taken on Ubuntu
  18.04 but viewed on a different system (16.04 and Windows).

  Installing a previous kernel version fixes the issue completely. I
  used UKUU Update Utility to install kernel 4.4 (the same that I use in
  Ubuntu 16.04 without issues) and upon a reboot with 4.4 running on
  18.04 everything displayed smoothly. So this indicates that the system
  might be using a sub-optimal colour depth with the newer kernel?

[Kernel-packages] [Bug 1749420] Re: Colour banding and artefacts appear system-wide on an Asus Zenbook UX303LA with Intel HD 4400 graphics

[Daniel van Vugt]

I guess we can answer that question by seeing the EDID for the LCD
panel.

Please try this:
  1. Log into Ubuntu on Xorg (or just 'Ubuntu' if there's no such option).
  2. Run this in a terminal: xrandr --verbose > xrandr.txt
  3. Attach xrandr.txt to this bug.

Title:
  Colour banding and artefacts appear system-wide on an Asus Zenbook
  UX303LA with Intel HD 4400 graphics

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  - Ubuntu 18.04 (with updates as of 14 Feb 2018).
  - Laptop: Asus Zenbook UX303
  - CPU: Intel i5 4210U
  - Graphics: Intel HD 4400

  Problem description: Colour artefacts and banding in all apps.
  Graphics, photos and videos display as though the colour range is
  improperly configured.

  See this photo of a 1080p video taken with a camera (poor quality, but
  illustrates the issue): https://ubuntucommunity.s3-us-
  
east-2.amazonaws.com/original/2X/c/c8f266715226953c6a77db6367ff9b7895784e35.jpg

  Look at the sky’s light colours. They display with smooth gradients on
  Ubuntu 16.04, but as the photo illustrates 18.04 seems to display the
  video with a smaller range of white colours. This is the most apparent
  with either very dark or very light colours. Even on window titlebars
  the banding is visible (displayed as lines with different shades of
  grey/black).

  Compared with a PrtSc shot of the same image:
  https://i.imgur.com/VkOSCaQ.png

  The artefacts are not present on PrtSc shots that are taken on Ubuntu
  18.04 but viewed on a different system (16.04 and Windows).

  Installing a previous kernel version fixes the issue completely. I
  used UKUU Update Utility to install kernel 4.4 (the same that I use in
  Ubuntu 16.04 without issues) and upon a reboot with 4.4 running on
  18.04 everything displayed smoothly. So this indicates that the system
  might be using a sub-optimal colour depth with the newer kernel?

[Daniel van Vugt]

Attached is the difference between kernel 4.7 and 4.8 in the Intel
graphics driver. It's still a big diff, but at least eliminates my above
theories about the cause of the regression. Now the main suspect, I
think, would be:

@@ -12095,21 +12181,11 @@ connected_sink_compute_bpp(struct intel_connector 
*connector,
pipe_config->pipe_bpp = connector->base.display_info.bpc*3;
}

-   /* Clamp bpp to default limit on screens without EDID 1.4 */
-   if (connector->base.display_info.bpc == 0) {
-   int type = connector->base.connector_type;
-   int clamp_bpp = 24;
-
-   /* Fall back to 18 bpp when DP sink capability is unknown. */
-   if (type == DRM_MODE_CONNECTOR_DisplayPort ||
-   type == DRM_MODE_CONNECTOR_eDP)
-   clamp_bpp = 18;
-
-   if (bpp > clamp_bpp) {
-   DRM_DEBUG_KMS("clamping display bpp (was %d) to default

Most of the call traces are indeed on stress-ng, so this may not be a
problem at all. It might be best if somebody from the kernel team can

  Call Trace messages in syslog with 4.4.0-116 kernel

Bug description:
  In doing regression testing of the 4.4.0-116 kernel with the server

  tested was an Intel NUC DC53427HYE. The complete test results are

Title:
  Call Trace messages in syslog with 4.4.0-116 kernel

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  In doing regression testing of the 4.4.0-116 kernel with the server
  certification tools, the miscellanea/call-trace-check test failed on
  one system. (Maybe more, too; this was the first system to finish the
  tests.) This test simply looks for the string "Call Trace" in
  /var/log/syslog, and there are 44 such call traces. The system being
  tested was an Intel NUC DC53427HYE. The complete test results are
  available here:

[Kernel-packages] [Bug 1703941] Re: bluetooth not work and wifi some time disable and enable

[Christopher M. Penalver]

Abhijeet Ravi Raj, thank you for reporting this and helping make Ubuntu
better.

1) Regarding bluetooth, this appears a known issue due to the vendor not 
providing upstream support:
https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1355096

Regarding WiFi:

2) Could you please provide the full computer model as noted on the
sticker of the computer itself (not from the Bug Description, or the
result of a terminal command)?

3) Is this something that started to happen after an update? If so,
which?

4) To see if this is already resolved in your release, could you please
update your HWE stack as per
https://wiki.ubuntu.com/Kernel/LTSEnablementStack and advise to the
results?

** Description changed:

- my bluetooth and wifi hardware is belongs to Ralink and its detail is
- rt3290, It problem is that it sometime auto disable till the hareware

Title:
  Call Trace messages in syslog with 4.4.0-116 kernel

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  In doing regression testing of the 4.4.0-116 kernel with the server
  certification tools, the miscellanea/call-trace-check test failed on
  one system. (Maybe more, too; this was the first system to finish the
  tests.) This test simply looks for the string "Call Trace" in
  /var/log/syslog, and there are 44 such call traces. The system being
  tested was an Intel NUC DC53427HYE. The complete test results are
  available here:

  https://certification.canonical.com/hardware/201508-19150/submission/127493/

  requested data

Bug description:
  [Impact]

   * Xenial with HWE kernel (matching new relesaes) and qemu without cloud
 archive (not matching new releases) could trigger hypercalls that are 
 not supported in xenials-qemu.

   * There is no "real" case other than kvm tests yet to trigger it yet, but 
 it is an easy and well contained fix, so we might fix proactively.

  [Test Case]

1. deploy xenial + HWE kernel on a ppc64el box
2. sudo apt-get install qemu-kvm -y
3. git clone --depth=1 
https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
4. cd kvm-unit-tests
5. ./configure --endian=little; make
6. sudo ppc64_cpu --smt=off
7. sudo ./run_tests -v

  [Regression Potential]

   * The changes are all upstream since a long time now (lowering the risk 
 of silly mistakes)
   * The changes are isolated to ppc, so in the worst case only this arch 
 should regress.
   * We implement new hcalls, so if anything there might be a regression if 
 software expected them to fail, but now breaks by them working (don't 
 think so given the nature of these hcalls).

[Kernel-packages] [Bug 1734327] Re: Kernel panic on a nfsroot system

[Joseph Salisbury]

I built a test kernel with the patch from Tetsuo.  The test kernel can be 
downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1734327

Can you test this kernel and see if it resolves this bug?

Note, to test this kernel, you need to install both the linux-image and
linux-image-extra .deb packages.

Thanks in advance!

  Kernel panic on a nfsroot system

Status in linux package in Ubuntu:

Bug description:
  == SRU Justification ==
  The following commit introduced a regression identified in bug 1734327:
  ac8f82a0b6d9 ("UBUNTU: SAUCE: LSM stacking: LSM: Infrastructure management of 
the remaining blobs")

  The regression causes a kernel panic to occur after multiple TCP connection 
  creations/closures to the localhost.  The bug was found using STAF RPC calls, 
  but is easily reproducible with SSH.

  A revert of commit ac8f82a0b6d9 is needed to resolve this bug.  However, 
commit 4ae2508f0bed
  also needs to be reverted because it depend on commit ac8f82a0b6d9.

  == Fix ==
  Revert 4ae2508f0bed ("UBUNTU: SAUCE: LSM stacking: add stacking support to 
apparmor network hooks")
  Revert ac8f82a0b6d9 ("UBUNTU: SAUCE: LSM stacking: LSM: Infrastructure 
management of the remaining blobs")

  == Test Case ==
  A test kernel was built with these two commits reverted and tested by the 
original bug reporter.
  The bug reporter states the test kernel resolved the bug.



  
  == Original Bug Description ==
  Summary:
  Kernel panic occurs after multiple TCP connection creations/closures to the 
localhost.
  The bug was found using STAF RPC calls, but is easily reproducible with SSH.
  The bug doesn't appear on an identical virtual machine booting from the disk.
  The bug is not reproducible on a similarly-prepared Ubuntu 16.04 machine.
  The bug is reproducible using an older 4.13.0-16-generic kernel
  Reproducible on multiple hardware types.
  Unable to create a kernel memory dump due to makedumpfile errors.
  apport-bug save attached.

  NFSRoot boot options:

  Software:
  OS: Ubuntu 17.10
  Kernel: 4.13.0-17-generic x86_64

  Reproduction steps:
  1. Boot a system from a nfsroot
  2. Configure password-less localhost ssh access
  3. Run a loop: `while true; do ssh localhost 'uname -a'; done`
  4. Wait for system to crash

Bug description:
  [Impact]
  After upgrading an Ubuntu/arm64 KVM host past xenial, your xenial-based 
guests will fail to boot.

  [Test Case]
  Boot a xenial cloud image with qemu-efi-aarch64 from artful/bionic.

  [Regression Risk]
  I've tested booting a xenial cloud image in bionic (ACPI mode), and 
regression tested w/ xenial's qemu-efi (DTB mode). I've regression tested on a 
Cavium ThunderX CRB1S, Caviumt ThunderX CRB2S and an APM X-Gene 2 Merlin board.

  Patches 1-5 change only code in the GICv3 driver. The xenial GA kernel
  only supported 2 GICv3 systems - the 1 socket and 2 socket variants of
  the Cavium ThunderX CRB - and I've regression tested on those systems.

  Patch 6 only adds new macro definitions.

  Patch 7 is restricted to devicetree code, except for a change to
  earlycon.c:param_setup_earlycon(). In the case that 'earlycon' is
  passed on the cmdline (vs. earlycon=something), this function used to
  return 0 - but now it will return -ENODEV on non-devicetree systems,
  which is a subtle API change. However, according to kernel-
  parameters.txt (and the code itself), 'earlycon' by itself is only
  valid on devicetree systems. Just to be sure, I booted an x86 system
  up w/ 'earlycon' with and without this series, and observed no
  difference.

  Patch 8 adds the SPCR table parser, but no caller to it yet. It also
  modifies the same earlycon code as Patch 7 - here it avoids earlycon
  init in the case that the devicetree-specific 'earlycon' was passed.
  As mentioned in my analysis Patch 7, this codepath is only supported
  for devicetree systems, and has been regression tested on x86.

  Patch 9 turns on CONFIG_ACPI_SPCR_TABLE - however, this driver will
  only be built for arm64. TBH, I'm not 100% sure how Kconfig knows not
  to build this for other archs - but I checked the logs, and there's no
  spcr.o built on other archs. (Not that that should be a problem - they
  would just grow a bit of unused code).

  Patch 10 only touches arm64-specific code, adding the call to
  parse_spcr(), so risk is limited to arm64.

  Patch 11 adds a new match method to the ARM-specific pl011 console
  driver, so regression risk to other architectures is negligible.

Bug description:
  From time to time, CPU vendors release updates to microcode that can
  be loaded into the CPU from the OS.  For x86, we have these updates
  available in the archive as amd64-microcode and intel-microcode.

  Sometimes, these microcode updates have addressed security issues with
  the CPU.  They almost certainly will again in the future.

  We should ensure that all users of Ubuntu on baremetal x86 receive
  these security updates, and have them applied to the CPU in early boot
  where at all feasible.

  Because these are hardware-dependent packages which we don't want to
  install except on baremetal (so: not in VMs or containers), the
  logical place to pull them into the system is via the kernel, so that
  only the kernel baremetal flavors pull them in.  This is analogous to
  linux-firmware, which is already a dependency of the linux-
  image-{lowlatency,generic} metapackages, and whose contents are
  applied to the hardware by the kernel similar to microcode.

  So, please update the linux-image-{lowlatency,generic} metapackages to
  add a dependency on amd64-microcode [amd64], intel-microcode [amd64],
  and the corresponding hwe metapackages also.

  Please time this change to coincide with the next updates of the
  microcode packages in the archive.

  I believe we will also need to promote the *-microcode packages to
  main from restricted as part of this (again, by analogy with linux-
  firmware).

Bug description:
  [Impact]
  If a dkms package is installed which has REMAKE_INITRD or the same setting 
has be manually configured by a user then when a kernel is removed its possible 
for an ".old-dkms" file to be left in /boot with no associated kernel.

  [Test Case]
  On a system with two old kernels and one new kernel available in -updates:
  1) install r8168-dkms
  2) install the dkms module for the old kernel e.g. 'sudo dkms install -m 
r8168 -v 8.041.00 -k 4.4.0-31-generic'
  3) upgrade your kernel e.g. "sudo apt install linux-image-generic'
  4) sudo apt autoremove
  5) observe something like "initrd.img-4.4.0-31-generic.old-dkms" in /boot 
without a corresponding "initrd.img-4.4.0-31-generic"

  With the version of dkms in -proposed, the .old-dkms file will be
  removed when the kernel is auto removed.

  [Regression Potential]
  Somebody out there might expect the .old-dkms file to be kept, but that seems 
like an odd expectation.

  One notices *.old-dkms files being left behind still sitting on the
  disk after purging the related kernel. This can cause /boot to become
  full, and when it gets really bad, even sudo apt-get autoremove won't
  fix the problem - only deleting the old-dkms files manually solves the
  problem.

  Note:  Filling up the /boot partition causes updates to fail.

  during installation

Status in Ubuntu on IBM z Systems:
  Confirmed
Status in console-setup package in Ubuntu:
  Incomplete
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  [Impact]

  console-setup continuously tries to open /dev/tty[1-6] on s390x, when
  such consoles do not exist on s390x.

  This can be seen on boot in the output from the initramfs, and during
  the installer.

  [Cause]

  It seems to me that the postinst of the console-setup is incorrect for
  s390, since on s390 Linux tty[1-6] do not exist in any modes (LPAR,
  z/VM, KVM)

  [Solution]
  I do not know what ACTIVE_CONSOLES should be set as, my guess is to set it 
to... "guess". Usually it should be slcp, but that depends on which consoles 
are configured/activated in the given KVM.

  [Testcase]
  On boot, scroll all the messages and makesure there are no error messages 
about inability to open /dev/tty*

  When testing MAAS on Bionic, we noticed sluggish performance that we

  After comparing the results from a run of the test suite on Xenial to
  a run on Bionic, we determined that the slowdowns had to do with DNS
  lookups. In particular, if MAAS attempts to resolve a hostname using
  getaddrinfo() and the call fails, on Xenial the negative result is
  returned in a fraction of a second. On Bionic, the negative result is
  returned in ~1.6 seconds, according to some measures.

[Kernel-packages] [Bug 1746806] Re: sssd appears to crash AWS c5 and m5 instances, cause 100% CPU

I tried out the 1052 proposed kernel on a C5 instance that runs
sssd/apparmor and it did not lock up.

  After upgrading to the Ubuntu EC2 AMI from 20180126 (specifically
  ami-79873901 in us-west-2) we have seen sssd hard locking c5 and m5
  EC2 instances after starting the service and CPU goes to 100%.

  We do not experience this issue with t2 or c4 instance types and we do
  not see this issue on any instance types using Ubuntu Cloud images
  from 20180109 or before. I have verified that this is kernel related
  as I booted an image that we created using the Ubuntu cloud image from
  20180109 which works fine on a c5. I then did a "apt update && apt
  install --only-upgrade linux-aws && systemctl disable sssd", rebooted
  the server, verified I was on the new kernel and started sssd with
  "systemctl start sssd" and the EC2 instance froze and Cloudwatch CPU
  usage for that instance went to 100%.

  I haven't been able to find much in the syslog, kern.log, journalctl
  logs, etc. The only thing I have been able to find is that when this
  happens I tend to see "^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@" in
  the syslog and sssd log files.  I have attached several log files and
  the output of a "apport-bug /usr/sbin/sssd". Let me know if you need
  anything else to help track this down.

  Thanks,
  Paul

When there will be a kernel with this patch included?

What about the live image? It's going to take months for a live

  Ubuntu 4.13.0-21.24-generic 4.13.13

  
  I have a Razer Blade Stealth 2016. The first Ubuntu I installed was Ubuntu 
17.04, which gave me this error after 2 weeks of usage. After that, I installed 
16.04 and used it for MONTHS without any problems, until it produced the same 
error this week. I think it has to do with the ubuntu updates, because I did 
one recently and one today, just before this problem. Could be a coincidence 
though.

  I notice the error when I try to save something on disk and it says me
  that the disk is in read-only mode:

  lz@lz:/var/log$ touch something
  touch: cannot touch 'something': Read-only file system

  Rebooting the ubuntu will give me a black terminal where I can run
  fsck /dev/nvm30n1p2 (something like that) and it fill fix a lot of
  orphaned inodes. The majority of time it boots back to the Ubuntu
  working good, but some times it boots to a broken ubuntu (no images,
  lots of things broken). I have to reinstall ubuntu then.

  Every time I reinstall my Ubuntu, I have to try lots of times until it
  installs without an Input/Output error. When it installs, I can use it
  for some hours without having the problem, but if I run the software
  updates, it ALWAYS crashes and enters in read-only mode, specifically
  in the part that is installing kernel updates.

  I noticed that Ubuntu installs updates automatically when they're for
  security reasons. Could this be the reason my Ubuntu worked for months
  without the problem, but then an update was applied and it broke?

  I thought that this bug was happening:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184 and tried
  different nvme_core.default_ps_max_latency_us= combinations, all them
  gave errors. I just changed to 0 and I had no error while using ubuntu
  (however I didn't test for a long time) but I still had the error
  after trying to update my ubuntu.

  My Samsung 512gb SSD is:

  SAMSUNG MZVLW512HMJP-0, FW REV: CXY7501Q

  on a Razer Blade Stealth.

  I also asked this on ask ubuntu, without success:
  https://askubuntu.com/questions/998471/razer-blade-stealth-disk-

  Please help me, as I need this computer to work on lots of things :c

Sadly issue returned with kernel 4.13.0-35. As i can see from changelog
some Spectre patches have been changed to different approach to fix this
issue. So this is probably reason for this behavior.

[Kernel-packages] [Bug 1749746] [NEW] DellEMC AMD servers hang when running IO stress on NVMe disks

[Sujith Pandel]

*** This bug is a security vulnerability ***

Private security bug reported:

Description:
On Ubuntu 16.04 running 4.13.0-32 kernel, when file IO stress is run on 
multiple NVMe disks (ext4 partitioned), system hangs with multiple kernel 
crashes in the logs.

Steps:
1. Setup a DellEMC AMD servers with a few NVMe disks.
2. Run the file IO stress on these disks for 24 hours.
3. Observe that the system goes un-reponsive after a few mins/hrs.

Additional Info:
* Stress ran fine for 24hrs with 4.12.0-041200-generic.

* Stress ran fine for 13hrs with 4.10.0-28-generic. Had to stop the run
manually due to some other reasons.

* Stress fails with linux-image-4.13.0-25-generic.

Attaching the logs.
Will update here once we have more data.

  == Comment from Hari Krishna Bathini ==

  There are quite a few commits (all available upstream) that are needed for
  crash tool to work fine. I think the right thing to do here would be to use
  the latest crash tool version 7.2.0 to go with the kernel update. Also, the
  below commit would be needed on top of 7.2.0 crash utility:

commit c8178eca9c74f81a7f803a58d339635cc152e8d9
Author: Dave Anderson 
Date:   Thu Nov 9 11:39:05 2017 -0500

  Update for support of Linux 4.14 and later PPC64 kernels where the
  hash page table geometry accomodates a larger virtual address range.
  Without the patch, the virtual-to-physical translation of user space
  virtual addresses by "vm -p", "vtop", and "rd -u" may generate an
  invalid translation or otherwise fail.
  (hbath...@linux.vnet.ibm.com)

  Similar thing holds true for makedumpfile tool..

  Thanks
  Hari

[Jim Carey]

For some reason, having done the process of removing nvidia, virtual
box, installing the 4.16 kernel, removing the 4.16 kernel, reinstalling
nvidia and virualbox, my system now boots the 4.13.0-32 kernel.  Not
sure what fixed it.

[Kernel-packages] [Bug 1746299] Re: update makedumpfile tool version to v1.6.3

[Thadeu Lima de Souza Cascardo]

Hi, Breno.

I will try to push makedumpfile, kexec-tools and crash on the basis that
those new versions are required to support new kernels as the ones that
come from linux-hwe. New version upgrades are allowed. Even though the
following link [1] mentions microreleases, and we would upgrade from
1.5.9 to 1.6.3, I believe the exception still applies.

However, that means that we will need to test it much more. So, I would
like your help with testing that combination on as many environments as
possible. If I give you a personal PPA with those packages, will you be
able to test it on different scenarios (NUMA systems, like ones with no
node 0), systems with large amounts of memory (512GiB and up), etc?

Thanks.
Cascardo.

Title:
  update makedumpfile tool version to v1.6.3

Status in The Ubuntu-power-systems project:
  In Progress
Status in makedumpfile package in Ubuntu:
  Fix Released

Bug description:
  [Impact]
  New upstream kernel versions, as those in linux-hwe package, require a newer 
makedumpfile to be supported. Otherwise, all copies fallback to copying the 
entire memory.

  [Test case]
  kdump-tools has been installed, system rebooted, then crash trigerred and 
verified that a small dump file was present on /var/crash/. Tested on amd64 and 
ppc64le.

  [Regression potential]
  Many other bug fixes have been included in the latest version of the package. 
The changes are supposed to fix these bugs, and have been tested as well. 
However, as the total of changes is not trivial, there is impact of regression 
that has been minimized by the tests done. Regression potential of not 
supporting older kernels has been tested with the kernels shipped on xenial and 
artful as well.

  ---Problem Description---
  update makedumpfile to latest version v1.6.3 that officially supports
  up to kernel version 4.14.8. Since makedumpfile is inherently backward 
compatible,
  this would not break existing functionality..

  Contact Information = hbath...@in.ibm.com

  ---uname output---
  na

  Machine Type = na

  ---Debugger---
  A debugger is not configured

  ---Steps to Reproduce---
   makedumpfile reports ""The kernel version is not supported" while generating 
vmcore
  Also, there is a possibility of bogus address translations in makedumpfile 
tool with
  missing upstream patches. Can't be so sure without an exhaustive testing. 
Instead,
  it would be a good idea to go with the version which officially supports the 
kernel
  version in question.

  Userspace tool common name: makedumpfile

  The userspace tool has the following bit modes: 64-bit

  Userspace rpm: makedumpfile

  Userspace tool obtained from project website:  na

  *Additional Instructions for hbath...@in.ibm.com:
  -Attach ltrace and strace of userspace application.

  == Comment: #1 - Hari Krishna Bathini  - 2018-01-30 
10:49:13 ==
  With kernel version updated to 4.13.0, please update makedumpfile tool
  version to 1.6.3 which officially supports up to kernel version 4.14.8 [1].

  Thanks
  Hari

  Samsung SSD corruption (fsck needed)

Bug description:
  Ubuntu 4.13.0-21.24-generic 4.13.13

  
  I have a Razer Blade Stealth 2016. The first Ubuntu I installed was Ubuntu 
17.04, which gave me this error after 2 weeks of usage. After that, I installed 
16.04 and used it for MONTHS without any problems, until it produced the same 
error this week. I think it has to do with the ubuntu updates, because I did 
one recently and one today, just before this problem. Could be a coincidence 
though.

  I notice the error when I try to save something on disk and it says me
  that the disk is in read-only mode:

  lz@lz:/var/log$ touch something
  touch: cannot touch 'something': Read-only file system

  Rebooting the ubuntu will give me a black terminal where I can run
  fsck /dev/nvm30n1p2 (something like that) and it fill fix a lot of
  orphaned inodes. The majority of time it boots back to the Ubuntu
  working good, but some times it boots to a broken ubuntu (no images,
  lots of things broken). I have to reinstall ubuntu then.

  Every time I reinstall my Ubuntu, I have to try lots of times until it
  installs without an Input/Output error. When it installs, I can use it
  for some hours without having the problem, but if I run the software
  updates, it ALWAYS crashes and enters in read-only mode, specifically
  in the part that is installing kernel updates.

  I noticed that Ubuntu installs updates automatically when they're for
  security reasons. Could this be the reason my Ubuntu worked for months
  without the problem, but then an update was applied and it broke?

  I thought that this bug was happening:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184 and tried
  different nvme_core.default_ps_max_latency_us= combinations, all them
  gave errors. I just changed to 0 and I had no error while using ubuntu
  (however I didn't test for a long time) but I still had the error
  after trying to update my ubuntu.

  My Samsung 512gb SSD is:

  SAMSUNG MZVLW512HMJP-0, FW REV: CXY7501Q

  on a Razer Blade Stealth.

  I also asked this on ask ubuntu, without success:
  https://askubuntu.com/questions/998471/razer-blade-stealth-disk-
  corruption-fsck-needed-probably-samsung-ssd-bug-afte

  Please help me, as I need this computer to work on lots of things :c

[Kernel-packages] [Bug 1746411] Re: [linux-oem] Fix out of bound VBT pin on CNP

[Timo Aaltonen]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'. If the problem still exists,
change the tag 'verification-needed-xenial' to 'verification-failed-
xenial'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  === SRU Justification ===
  [Impact]
  i915 crashed when probing for VBT pin. No graphics output after that.

  [Test Case]
  Enable Legacy ROM boot option in BIOS. Screen goes blank.
  Cherrypick fixes can solve the issue. 

  [Fix]
  Handle out of bounds pin value more appropriately.
  Patches from Jani are most refactoring, but the fix we want depends on
  them.
  Patches from Rogrigo are the fixes we want. These patches are also
  picked base on his suggestion,
  https://bugs.freedesktop.org/show_bug.cgi?id=104139#c7

  [Regression Potential]
  Low. CNL and CNP are still quite new. These commits are limited to them.

  [Impact]
  GRE overlay networks can't carry traffic with MTU > 1500

  [Test Case]
  sudo add-apt-repository cloud-archive:pike
  sudo apt update
  sudo apt install openvswitch-switch
  sudo ovs-vsctl add-br br-tun
  sudo ovs-vsctl add-port br-tun gre0 -- set interface gre0 type=gre 
options:remote_ip=10.100.1.1

  gre_sys device will be configured with MTU 1472.

  sudo ip link set gre_sys mtu 65000

  will fail with EINVAL.

  [Regression Potential]

  [Bug Report]

  Under Linux 4.13 its not possible to configure GRE tunnel devices with
  a MTU larger than 1500; this impacts on Open vSwitch (which creates
  tunnel devices for GRE overlay networking) and the ip tools.

  The kernel will error with:

    gre_sys: Invalid MTU 65000 requested, hw max 1500

  The side effect of this is that if overlay networks are configured
  with high MTUs, the gre devices fragment the packets and networking is
  generally slow/broken.

  This is resolved as part of the upcoming 4.15 kernel under:

Bug description:
  Lenovo introduced 4 new TrackPoint compatible sticks those only
  support the minimum commands described in the spec, which has been
  used in the current Windows driver.

  Legacy TrackPoint: 0101 – 0E01

  ALPS: 0102 – FF02

  ELAN:0103 – FF03

  NXP: 0104 – FF04

  TrackPoint (ID: 01/02) report 0 button when reading the EXT_BUTTON
  command.

  Setting middle button enabled to make it work.

  Upstream patch:
  commit f5d07b9e98022d50720e38aa936fc11c67868ece
  Author: Aaron Ma 
  Date:   Fri Jan 19 09:43:39 2018 -0800

  Input: trackpoint - force 3 buttons if 0 button is reported
  
  Lenovo introduced trackpoint compatible sticks with minimum PS/2 commands.
  They supposed to reply with 0x02, 0x03, or 0x04 in response to the
  "Read Extended ID" command, so we would know not to try certain extended
  commands. Unfortunately even some trackpoints reporting the original IBM
  version (0x01 firmware 0x0e) now respond with incorrect data to the "Get
  Extended Buttons" command:
  
   thinkpad_acpi: ThinkPad BIOS R0DET87W (1.87 ), EC unknown
   thinkpad_acpi: Lenovo ThinkPad E470, model 20H1004SGE
  
   psmouse serio2: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 0/0
  
  Since there are no trackpoints without buttons, let's assume the 
trackpoint
  has 3 buttons when we get 0 response to the extended buttons query.
