dmesg log containing several GPU lockups

Upgrading xf86-video-ati to 7.2 has caused very frequent GPU lockups on my
machine (one after the other), after a while even causing my machine to
spontaneously reboot.

I'm using a Radeon HD7850, on a fully-updated 64bit Arch Linux installation
(Linux 3.10.5, Xserver 1.14.2). Attached is a dmesg from when the GPU locked-up
but I managed to switch to a TTY console, after which my system didn't lock-up
and I could collect the dmesg (but forgot Xorg.log).

My xrandr configuration:
