Example screen image when failing

Forwarding this bug from a Canonical reporter:
https://bugs.edge.launchpad.net/ubuntu/+source/xserver-xorg-driver-ati/+bug/324234

Selecting the first VT (ctl-alt-F1) results in flashing garbage on screen, and sometimes (one in three tests) a freeze.

Attached logs are from the first reboot after the freeze.

The gdm log shows some xserver output which might be relevant...

...
