[Bug 1117499] Re: killall -9 firefox fails to work in raring


Steve Langasek, thank you for the clarification. Could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

  killall -9 firefox fails to work in raring

Status in “linux” package in Ubuntu:

Bug description:
  Something is wrong in raring.  After upgrade, I have twice run into a
  problem where firefox takes over 100% of a CPU, X takes 100% of
  another, and the desktop is completely unresponsive (even to the point
  that the cursor doesn't move and I can't switch VTs).

  The reason I'm filing this bug against the kernel, however, is that
  this time I decided to kill -9 firefox... and *it's not working*.

  So something is seriously wrong with this kernel, because kill -9
  shouldn't fail.

  More debugging information will be available once I figure out how to successfully recover the desktop session.
