[Bug 348428] Re: Swithing to another user and then to anything else, freezes laptop. Jaunty

[ichudov]

I did run the X server that crashes (the guest one) under GDB, as
outlined on https://wiki.ubuntu.com/X/Backtracing

I save output to file (attached) and did say backtrace full. So here it
is.

Looks like it occurs in drm_intel_bo_unreference, which, sadly, likely
suggests a memory corruption elsewhere. drm_intel_bo_unreference is
called by gen4_render_state_cleanup.
