[Bug 1358153] Re: Keyboard and touchpad randomly crash after boot

 

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.17 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  Keyboard and touchpad randomly crash after boot

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After the OS boots, the keyboard and the touchpad crash and I cannot
  even type my password to log in.

  This bug is a quite old one, and present in multiple distributions, so
  I think it might be a kernel bug, but I am not sure.

  The OS itself doesn't freeze, I can use a mouse instead of the
  touchpad, and if I had an external USB keyboard, it would work also.

  One more thing: when this problem occurs, I cannot simply reboot or
  turn off the machine by selecting the appropriate option from the
  system menu, because this way the system hangs with a black screen. I
  can turn off only by pressing the power-off button.

  I am using Ubuntu 14.04 with this kernel: Ubuntu 3.13.0-32.57-generic
  3.13.11.4
