Title:
  utopic: Watchdog detected hard LOCKUP on cpu

Status in linux package in Ubuntu:
  Expired

Bug description:
  After upgrading to Utopic, I have experienced two "crashes" (a few
  hours apart).  I am unable to identify the trigger.  Searching for
  similar bugs either apply to earlier releases of [K]Ubuntu or pertain
  to hardware that I do not have.  I say my system "crashes" as I never
  wait long enough for the system to actually crash.  I have had to
  reset the system both times in order to generate a response.  In both
  instances, the mouse was still moving the cursor but no action by the
  mouse buttons or keyboard typing generated a response.  Also, the
  machine would not respond to soft reset.  A hard reset (prolonged
  depressing of the power button) was necessary to regain control.

  I have never experienced this issue before (on any hardware type) so I
  have limited information to offer (as I don't know where to look).  I
  have attached the relevant syslog entries for the last crash.  It is
  here that I determined the CPU lockups.  First CPU 4 had a hard
  lockup, proceeded by a soft lockup on CPU 1.

  Please let me know what else to gather when this occurs again.
