  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

[Daniel van Vugt]

Oh. Maybe this is a bluez regression. It looks like the shell code has
been rewritten and that's what is not working. Sometimes the test
commands from python-dbusmock don't get through.

  However the failure only occurs in the Ubuntu package of python-
  dbusmock. It does not occur with the upstream git repo (run as 'tests

Title:
  [xhci_hcd] HC died · USB controller died, reboot necessary

Status in linux package in Ubuntu:
  Expired

Bug description:
  * Ubuntu release: 17.04
  * uname -r: 4.10.0-42-generic
  * Expected behaviour: the USB ports run well
  * What happens: the USB ports are randomly killed from time to time

  * Explanation:
  The xhci_hcd driver reports that the xHCI host is not responding to a stop 
endpoint command. The USB host controller is then shut down and all USB ports 
are left dead until a reboot is performed. This is not immediate nor 
predictable --- sometimes, it can be days before it happens; sometimes it is 
just hours.

  If I understood correctly, there is no way to reload the kernel module
  of the USB driver, because it is baked into the kernel at compile
  time. Something like that? :)

  When rebooting, the shutdown process completes (it reports a "shutdown
  target achieved" or similar), but is unable to unmount the /home/user
  partition. Therefore, the system does not shutdown unless I press the
  power button (hard shutdown). I do not know if there is a way to get a
  TTY at that point to manually unmount the partition. The home folder
  is encrypted... I do not know if this has something to do with it, but
  this error only occurs when the USB HC is killed.

  I suspect the USB problem has to do with an external USB hub by TP-
  LINK. It seems to only fail when this device is connected. The hub
  model is UH400, by TP-LINK.

  Anything I can add, just ask for it!
  Thanks a lot!

[Kernel-packages] [Bug 1746340] Re: Samsung SSD corruption (fsck needed)

[Lucas Zanella]

I compiled a kernel myself apllying the patcch and using make deb-pkg
and got these files:

linux-headers-4.15.4_4.15.4-4_amd64.deb
linux-image-4.15.4_4.15.4-4_amd64.deb
linux-image-4.15.4-dbg_4.15.4-4_amd64.deb
linux-libc-dev_4.15.4-4_amd64.deb

but you don't have image...dbg neither libc, and you have image-extra
and headers...generic. What's the difference? Will mine work? If not,
how do I get your 4 files exactly?

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

  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

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

[Daniel van Vugt]

Thanks for those files. They seem to confirm that the kernel change in
comment #16 is the cause of the regression.

So the kernel is basically doing the right thing in trying to support
all screen types. Only your screen contains inadequate firmware to be
able to tell the kernel what it really is. So the solution is probably
to detect your particular screen model and apply a workaround just for
that model (equivalent to ASUS providing a custom display driver in
Windows).

It is unfortunate (for you) that hardly anyone else will experience this
bug. Even on other 6-bit panels, many people won't have a problem (and I
have tried on a few systems). So you're just a bit unlucky with this
particular LCD panel. But it sounds like a fix is now coming :)

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 1502238] Re: bridge does not forward neighbor solicitation packets

[Ruben Portier]

I also suffer from this issue for a long time. All my computers work
fine, however my Ubuntu homeserver running virtual machines have
problems when I try to connect to them over IPv6 locally. They work at
first and then suddenly it stops working due to the neighbour
advertisement not reaching my router.

I can see the advertisement is being send on the actual host or vm's,
but that packet is not visible on the router or the clients. So this is
a bug in the bridge I guess? I really need a fix for this, can someone
explain the workaround for me?

Also, why is this bug not updated anymore? Was it fixed, or not
reproducable?

  I have made a little investigation.

  Ubuntu 16.04.3 LTS, kernel 4.10.0-28, lpfc 11.2.0.2 - no problem.
  Ubuntu 17.10.1, kernel 4.13.0-21, lpfc 11.4.0.1 - problem.
  Debian 9.3, kernel 4.9.0-4, lpfc 11.2.0.0 - no problem.
  Fedora 27, kernel 4.13.9-300, lpfc 11.4.0.1 - problem.
  Proxmox 5.0, kernel 4.10.15-1, lpfc 11.2.0.2 - no problem.
  Proxmox 5.1, kernel 4.13.13-5, lpfc 11.4.0.1 - problem.

  Another user with this problem said that if fiber switch is added
  between the server and the storage it's working as expected.

  I think problem is in lpfc.ko 11.4.0.1. Any kernel (4.13 now) that has
  this module version is affected. Broadcom support confirmed that bug
  and suggested to update module. But Broadcom supports only RHEL and
  SLES. I tried to compile, but no luck. Please, could you update
  lpfc.ko module in linux-image-generic package?

  There are version 11.4.142.21 for SLES 12 and 11.4.204.11 for RHEL 6
  and 7 on Broadcom site.

  Thanks.

[Kernel-packages] [Bug 1748678] Re: Intel graphics timeout, possibly caused wifi network to fail

[Daniel Llewellyn]

Further, I've managed to cause two system lock-ups, which I do not have
logs for because the lock-ups were so severe that the logging system
didn't record the kernel logs before death. I therefore cannot attribute
those two lockups to this issue for now. I've set-up netconsole now to
try to gather logs from these lock-ups so that I can definitively
attribute or rule them out.

  My wifi network device stopped responding, unable to list any local

Bug description:
  I have a Dell Venue 11 Pro 7139, and when I installed artful on it
  (before release) it worked fine. Recently (over the xmas break I think
  but I'm not sure; this is not a machine I intended to pay too much
  attention to) the kernel moved from 4.12 to 4.13, and the touchscreen
  has stopped working.

  I _think_ the last kernel to work was 4.12.0-13. I haven't done any
  sort of bisection though.

[Kernel-packages] [Bug 1746418] Re: System freezes when starting Xorg after installing linux-image-4.13.0-32-generic

[FaberfoX]

I've been having this same issue on ubuntu mate 17.10 on a thinkpad
T450s since kernel 4.13.0-25, and was booting with previous 4.13.0-21.
Just tried #14 suggestion (adding noibpb) and it fixed it here.

Title:
  System freezes when starting Xorg after installing linux-
  image-4.13.0-32-generic

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  My laptop (Lenovo T440) freezes when starting Xorg (lightdm) only
  after installing the latest ubuntu kernel for 17.10, linux-
  image-4.13.0-32-generic.

  Am running Xorg instead of MIR due to MIR crashing when I initially
  upgraded from 17.04 to 17.10, but that's a different problem for a
  different day. It's been running with Xorg stably for at least 2-3
  months.

  If I boot with the previous kernel version on my /boot (linux-
  image-4.13.0-25-generic), everything works fine.

  If I boot with the latest mainline kernel from the Ubuntu mainline
  repo (4.15.0), everything works.

  Using grub's option to run "Recovery Mode" for the 4.13.0-32 kernel, I
  am able to use the CLI and access the encrypted root filesystem, which
  is how I generated the apport repo that's attached. It's only when
  telling it to continue Normal booting that it freezes, which is why I
  suspect the problem of being Xorg.

  When the system freezes, the fan starts to spin up. I cannot switch
  virtual consoles using CTRL-ALT-F{1-7}. CTRL-ALT-DEL pressed
  repeatedly doesn't do anything. To reboot, I have to hold the power
  button until the system powers off.

[Kernel-packages] [Bug 1584557] Re: Seagate external drive causes SCSI bus resets when UAS enabled

[Skyman]

@Kai-Heng Feng: Thanks for your fast reply!
Does this mean, that UAS just will be disabled (slow disk) or is it like a fix?
I will give it a try as soon as possible. Is there a kernel version for 16.04.3 
LTS besides the mainline kernel?

[Kernel-packages] [Bug 1584557] Re: Seagate external drive causes SCSI bus resets when UAS enabled

[Skyman]

I'm also seeing this issue with a Maxtor Seagate 1 TB external USB 3 hard drive 
on HP Pavilion Desktop PC 570-p0xx
System is Kubuntu 16.04.3 LTS with Kernel 4.13.0-32-generic

The workaround/quirk from the original post makes the errors go away,
but the device is really slow.

lsusb output
Bus 005 Device 003: ID 0bc2:61b6 Seagate RSS LLC

Drive is brand new and has no SMART errors.

Output of lshw is attached. If you need any other informations please
let me know. But I could take some _weeks_ untill I will have access to
this machine again.

[Kernel-packages] [Bug 1675540] Re: i2c i2c-1: sendbytes: NAK bailout.

[Serhiy Zahoriya]

I'm getting this on a 14.04 production server without nouveau and X.
Can't test newer kernel since it's a production server. It started
happening after upgrade from 3.13.something to 4.4.0-112.

  [x86_64] Kernel panic when building on NFS in VM

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Since around begin of December (definitely before any KPTI was
  merged), I'm having problems building AOSP on an NFS share that is
  mounted in a VM with Ubuntu 16.04.3. After some minutes the system
  freezes completely, the SSH session becomes unresponsive and I can't
  open a new one. Logging in via virt-manager's UI isn't possible
  either.

  When connecting to serial port, I got the following kernel panic stack trace:

Title:
  Samsung SSD corruption (fsck needed)

Status in linux package in Ubuntu:
  Confirmed

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

  
  lz@lz:/var/log$ cat syslog

  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:

  corruption-fsck-needed-probably-samsung-ssd-bug-afte

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