Public bug reported: Ubuntu 11.04 running on a Fujitsu Lifebook T901 occasionally crashes at random points in time. The image remains on the screen, but the keyboard and mouse stop working, the fans turn off, and the hard drive stops spinning.
I haven't yet been able to guess what the problem is. Some suspicious kernel messages are: [ 1034.337077] polkit-gnome-au[1374]: segfault at 9 ip 00007f118afcd9d8 sp 00007fffde27d210 error 4 in libglib-2.0.so.0.2800.6[7f118afa6000+ed000] [ 496.205781] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id [16639.675560] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 1261669, at 1261669], missed IRQ?
