I'm running the latest git from Linus's tree with xf86-video-ati libdrm and mesa from git
The lockup seems to happen when video is playing. It's Xv rather than vdpau that seems to cause this

Does setting the env var RADEON_VA=0 in your /etc/environment fix the issue? This looks like a mesa issue.
I've not had another lockup since doing this
