Kernel output after lockup detection
Dual 1080p monitor setup using Sapphire HD5770 locks up after a few minutes of browsing with Chrome. gnome-shell runs at 100% CPU after lock up with an unresponsive display, except for mouse movement.
Was stable before recent fedora core 15 updates.

Looks similar to https://bugzilla.kernel.org/show_bug.cgi?id=38792
The regression seems to only affect xorg-x11-server-Xorg-1.10.3-1.fc15 and cannot be replicated after downgrading to xorg-x11-server-Xorg-1.10.1-14.fc15

Can you work with the Fedora developers to further isolate which change introduced / triggered the problem?
