[Dani <1358153@xxxxxxxxxxxxxxxxxx>]

The first Ubuntu release affected by this bug is 12.04 (I have tested
with an i386 Live CD).

Unfortunately I couldn't log any backtrace. If I boot in recovery mode,
a recovery menu shows up. If I wait too long, the keyboard crashes so I
cannot do anything. If I choose something quickly from the recovery
menu, then the keyboard won't crash, so there is no sense in logging a
backtrace.

With a crashed keyboard I cannot even change to another tty.

And I found out that the laptop functions (e. g. Fn + F1, F2, etc. for
wifi, brightness, volume, etc.) still work with a crashed keyboard.

** Changed in: linux (Ubuntu)
       Status: Incomplete => Confirmed

Title:
  Keyboard and touchpad randomly crash after boot

Status in “linux” package in Ubuntu:
  Confirmed

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
