Hi all

I just encountered this oops with 2.6.1_rc1-mm1. It did not lockup the
machine though. It continued to boot and start x, though in a very small
resolution. Maybe its related to the ati-driver for my Radeon 9600 card?
I am not sure what might have triggered this oops. Any hints where to
start looking?

Also attached to this email is the full dmesg, .config, and ksymoops
output.
