[Bug 329860] Re: xorg intel crashes on console switch with UXA enabled

[epv]

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  jaunty x86_64, xserver-xorg-video-intel xserver-xorg-video-intel  2:2.6.1-1ubuntu2 
  00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
  (pci id 8086:2a02) - lenovo x61 tablet.
  
  The X server crashes with:
  Feb 14 18:26:26 hostname kernel: [  252.148399] [drm:i915_gem_execbuffer] *ERROR* Execbuf while VT-switched.
  whenever a console switch happens (either by ctrl-alt-Fn or by chvt command.)
  
  It does not crash on console switch if UXA is not enabled via Option
  "AccelMethod" "UXA" in Device section of xorg.conf. (however without
  UXA, graphics performance is very bad)
  
+ Update: it also only crashes if dri(?) is in use: if I shut off compiz
+ (which is used by default) with "metacity --replace", the X server then
+ survives console switches.
+ 
   In particular this causes suspend/resume to fail because the power
  manager tries to chvt to a text console on suspend.
  
  syslog excerpt:
  Feb 15 13:34:15 hostname kernel: [20931.947721] [drm:i915_gem_execbuffer] *ERROR* Execbuf while VT-switched.
  Feb 15 13:34:15 hostname kernel: [20931.949764] [drm:i915_gem_execbuffer] *ERROR* Execbuf while VT-switched.
  Feb 15 13:34:15 hostname gdm[22637]: WARNING: gdm_slave_xioerror_handler: Fatal X error - Restarting :0
  
  nothing shows up in Xorg.0.log
