[Igor Izyumin <838958@xxxxxxxxxxxxxxxxxx>]

Public bug reported:

During use, X randomly crashes and restarts.  This does not seem to be
related to anything the user is doing at the time.  Syslog indicates
some interesting things happening with the bcm5974 driver when the crash
occurs.  However, the same behavior also often occurs without resulting
in a crash.  In the attached log files, the crash occurred at 09:41:29.

This is what syslog looks like:
