This bug still exists. Yesterday, we had three kernel freezes within 1h.
Netconsole output was pretty much the same as in comment #14. The server had to
be restarted using power off switch. Current versions:
Kernel: 3.8.0
Mesa: 9.1.7
xf86-video-ati: compiled for 1.13.3, module version = 7.1.0

These are the latest stable versions for Ubuntu 12.04LTS. We would not update
the server to XorgOnTheEdge versions due to the high risk of broken X system.

In addition to the many and various attachments of this bug notification, what
information is required to identify the root cause of this painful bug? And how
can we retrieve it having in mind a freezing system, which cannot write
information on the disks?
