Title:
  complete freeze

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  the system completely freezes say 2-3 times a week. 
  The freeze is complete, I mean:

  1) screen frozen, mouse and keyboard don't react
  2) alt + f1 won't do anything
  3) machine won't respond to ping (normally it responds)
  4) cltr + alt R E I S U B doesn't work (normally it works)

  I am not able to reproduce this bug. There is no particular action or circustances that is evident to trigger the bug.
  After power cycle, looking at syslog, kern.log and Xorg.{0,1}.log I don't see any meaningful error message.

  I had a look at bug #993187, I tried kenel 3.3.6 as suggested. I
  didn't experience any freeze, but I found that kernel to have many
  other bugs, so I didn't use it for long enough to be sure that the
  freezes won't occur again.

  If I can do anything more to provide useful debug information, just
  let me know.
