I was also affected from that issue. Finally it seems that I found in my
case a solution. The "Memory Frequency Limiter" in BIOS was set to
'AUTO' and I changed it to one of the lowest values. Since than my
system runs stable.

Title:
  Kernel Hard Freezing Very Often

Status in The Linux Kernel:
  Confirmed
Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux” package in openSUSE:
  Invalid

Bug description:
  I (and others in the forums) are experiencing MANY hard freezes in
  Ubuntu since upgrading to Kernel 3.0. Here is as much information as I
  can give now but I'll run anything (including the possibility of
  allowing a remote connect) to diagnose this problem as I think it is
  serious and has the potential to ruining machines as I'm frequently
  having to hard shut down which of course runs the possibility of
  damaging a hard drive.

  Problem: Hard freeze very often (I've had as many as 5 in an hour).
  Hard freeze definition from me:

  1. Mouse stops moving
  2. Keyboard actions have no response (including alt+cntrl+f1)
  3. Hard drive spins for a shor time but then stops
  4. Only way to fix is hard shut down

  What's been done:

  1. Checked logs (willing to provide any but I couldn't see any problem)
  2. Tried finding out if software is triggering it, seems to be random, could be wrong

  
  Again I think that this is a major problem so I'll do whatever it takes to provide information. Thank you in advance
