[Bug 370292] Re: [i855] Jaunty - X freezing on intel 855GM - MTRR issue (UXA/EXA)

[Bryce Harrington]

** Description changed:

  Running Jaunty on a Panasonic CF-R3 notebook with intel 855GM graphics
  chipset and pentium M processor. X (running compiz) will completely
  freeze seemingly randomly (fairly often though - easily 5 times a day),
  necessitating a hardware restart (or REISUB) although the mouse pointer
  is still responsive and disk activity is still continuing. Another
  generic intel driver freeze it would seem.
  
  I've tried the usual suspects with no avail:
  happens on both UXA and EXA
  with and without "MigrationHeuristics" "greedy"
  
  Turning DRI off seems to fix the issue though.
  
  Taking a look at my /var/log/kern.log, it seems that every time these lockups occur i'm getting a kernel log error of:
  Apr 29 12:49:26 mike-laptop kernel: [ 1032.985907] mtrr: no MTRR for e8000000,8000000 found
