[Mathieu Trudel-Lapierre <mathieu.tl@xxxxxxxxx>]

There were mentions of it happening after a resume from hibernate. Teo,
could you please confirm whether or not you've used hibernate again and
if it has triggered the bug? You mention later that it happens randomly,
but I just want to make it very certain that it can't be reliably
triggered by hibernation... rather than assuming anything.

To pinpoint this to an update that could have caused this issue, it
would be useful to have /var/log/apt/history.log for 2014-08-05 and a
few days earlier, if you still have that; along with if you remember
when the computer had last been rebooted before you did last reboot you
mention in this bug report. I realize this is a long time ago, but if
you remember, or if you usually shut down your computer every few days,
etc. then it can help figuring out from the apt history log whether a
specific package was updated around the same time and could be the cause
of the issue, or be a trigger for a BIOS bug.

Meaningful packages could still be acpi-support, linux, etc...

Thanks!

Title:
  [REGRESSION 2014-08] Volume up/down keys, and printScreen key, have
  stopped working

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  All of a sudden, the volume keys from the keyboard have stopped
  working.

  The volume control on the top right corner of the screen does work if
  used with the mouse.

  I have both an external usb keyboard with dedicated volume + and -
  keys, and the builtin laptop keyboard where the volume +/-keys are the
  combination of the Fn key plus the up/down arrows.

  All these used to work up to a few minutes ago. Now none of them works.
  I think they stopped working with the last reboot.
