[Kernel-packages] [Bug 1945590] Re: Thinkpad E14 Gen2: Kernel panic with trackpad and trackpoint enabled

2022-01-13 Thread Christo 
Not a long term fix but just proposing this as this saved me from not
booting in pop_os! 21.10.

Disable either the trackpad or trackpoint in BIOS. I disabled my
trackpoint and I am able to boot again.

Just so that other users who end up here have some temporary workaround,
as to update the kernel to fix this requires booting off usb or with
this method.

  Thinkpad E14 Gen2: Kernel panic with trackpad and trackpoint enabled

  Confirmed
Status in linux source package in Impish:
  Fix Committed
Status in linux source package in Jammy:
  Confirmed

Bug description:
  [Impact]

  On some thinkpads we may get a kernel panic at boot, because the
  elantech driver (trakcpad) can trigger out-of-bounds access in the
  stack.

  [Test case]

  Simply boot the kernel on one of the affected systems (e.g., Thinkpad
  E14 Gen2).

  [Fix]

  Prevent the stack out of bound access by applying the following
  upstream commit (from linux-next):

  1d72d9f960cc ("Input: elantech - fix stack out of bound access in
  elantech_change_report_id()")

  [Regression potential]

  The fix is touching the elantech driver, so we could only see
  regressions with this specific trackpad/mouse driver.

  [Original bug report]

  I installed the Ubuntu 21.10 beta and as soon as I boot I get the
  kernel panic that I am attaching.

  I also installed Ubuntu 21.04 and upgraded, as soon as I boot with the
  5.13 kernel I get the same problem, disabling the trackpad and
  trackpoint in the bios the problem disappears.

  Everything works with the 5.11 kernel.
  I remain available for further details and sorry for my lack of experience.
