Comment 1 for bug 692073

I am suffering from this bug with similar configurations to OP. Fglrx on 64 bit maveric. I would like to add that this is an Xserver crash not a reboot.

here is the critical part of the dmesg:

if i get time i'll test with the open source drivers at some point and see if the issue persists.
