[Kernel-packages] [Bug 1747597] [NEW] Number of processes exploded after upgrade to 4.13.0-32-generic

2018-02-06 Thread Marc Pignat

Public bug reported:

After an update from 4.10.0-40-generic to 4.13.0-32-generic (ubuntu
16.04 + hwe kernel), the number of process when doing IO on my machine
has exploded.

Before the update, maximum number of process : 284
After the update, doing a simple rsync to an external disk : 771

The system is now unstable and crashes. The processes are hundreds of
"kworker".

Please let me know if there is something more needed.

[Kernel-packages] [Bug 1746740] Re: XPS13 L322X Bionic (daily dev) touchpad laggy

2018-02-06 Thread Bib

Just tried : neither this issue with Trusty K4.4.0-112 nor K4.15.1 real 
installs.
Only met it with Bionic-dev-Live-K4. I also tried the Live USB with 
acpi_osi=Linux as seen (but not mandatory) in my usual /etc/default/grub, with 
no difference : touchpad cursor still laggy, often locks for a while. I noticed 
that when the touchpad is glued in position on the screen, it is still 
responsive on right and bottom sides, although the option ~scroll on sides~ is 
disabled by default in Devices settings. Changing the option as no effect, 
neither as disabling default enabled 2-Fingers-Scroll.
An other strange issue I met with the Live USB : when I reboot from Live, I 
can't go back in Live with my BIOS F12 Select boot drive: even when I select 
USB Live, then the usual grub menu is displayed. I have to completely shutdown 
the laptop so that USB boot selection works, when this is not the case when I 
reboot from usual installed Trusty.
I ran these tests with a new Bionic USB stick created from a Live Bionic 
session, itself running from the first Bionic key (that was created from an 
real Xenial install on another machine).

[Kernel-packages] [Bug 1734147] Re: corrupted BIOS due to Intel SPI bug in kernel

Sorry for the late response. It even doesn't do POST anymore. I turn it
on and all it does is, to start the fan at full power.

Title:
corrupted BIOS due to Intel SPI bug in kernel

Status in Linux:
Unknown
Status in linux package in Ubuntu:
Fix Released
Status in linux-hwe-edge source package in Xenial:
Fix Released
Status in linux-oem source package in Xenial:

Status in linux source package in Artful:

Bug description:
An update to linux kernel on Ubuntu 17.10 that enabled the Intel SPI
drivers results in a serial flash that is read only in Intel Broadwell
and Haswell machines with serial flashes with SPI_NOR_HAS_LOCK set.

Symptoms:
* BIOS settings cannot be saved
* USB Boot impossible
* EFI entries read-only.

---

Fix: The issue was fixed in kernel version 4.13.0-21 by configuring
the kernel so it is not compiled with Intel SPI support. But previous
affected machines still suffered from a broken BIOS.

Repair: If you still can boot into Ubuntu, you can recover your BIOS
with the following steps:

1. Boot into Ubuntu
2. Download
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
3. Install the downloaded package:
$ sudo dpkg -i
linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
4. Make sure the kernel is installed without any error. Once installed,
reboot.
5. At grub, choose the newly installed kernel. You can choose the "recovery"
mode.
6. Reboot and go to BIOS settings to confirm your BIOS has been recovered.
7. In case your BIOS is not recovered, reboot to the new kernel, then reboot
*once again* to the new kernel, do not enter BIOS settings before the reboot.
After the second reboot, check BIOS.
8. If your BIOS issue remains, download another kernel from
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb,
and use dpkg to install it, then repeat steps 4 to 6.

After your BIOS is fixed, the kernel packages you just installed are
no longer needed, you can remove it by running 'sudo dpkg -r linux-
image-4.15.0-041500rc6-generic'.

The patch used to build the linux v4.15 kernel in step 8 can be found
at https://goo.gl/xUKJFR.

Test Case: Fix has been verified by our HWE team on affected hardware.

Regression Potential: Minimal, it's unlikely anyone is actually doing
anything which requires this driver.

Original Description:

Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
reported a corrupted BIOS.

It's not possible to save new settings in BIOS anymore and after
rebooting, the system starts with the old settings.

Moreover (and most important) USB booting is not possible anymore
since USB is not recognized. It's very serious, since our machines do
not have a CDROM.

Lenovo forums at the moment are full of topics regading this issue.

Thank you!!
