[Bug 359931] Re: Jaunty intermittently freezes on Lenovo X61s related to graphics activity

[Bryce Harrington]

** Description changed:

  I'm getting occasional hangs on my X61s (3-4 times/day); the only common
  thread is that it happens during heavy graphics activity (e.g. flipping
  between VT's, zooming images in Firefox, browsing through photos).
  
  After the hang, the mouse pointer is nonresponsive and I can't switch
  out of X with Ctrl-Alt-F1. The disk activity LED does flicker when I
  hold the power button to force powerdown, though I'm not sure that this
  indicates the kernel is alive at some level.
  
  xserver-xorg-video-intel version is 2:2.6.3-0ubuntu (Jaunty). Bug wasn't
  present on Intrepid.
  
  I'm not certain that this is an Intel/X problem, but as mentioned above,
  graphics activity is the only commonality between the hangs.
  
  Any suggestions for how to narrow this down would be appreciated.
