[Bug 1386518] Re: utopic: Watchdog detected hard LOCKUP on cpu

  Thread Previous • Date Previous • • Thread Next 
apport information

** Tags added: apport-collected utopic

** Description changed:

  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.
