Yesterday I updated from the xorg-edgers ppa and the bug seems to be gone now. I even set the semaphore parameter to "0", which was a sure way to trigger this problem, and now there are no error messages about GPU hangs in dmesg.

This Phoronix article also suggests that this problem was fixed in mesa 7.11-devel, not in the kernel:

Right now I have the latest xorg-edgers packages with kernel 2.6.39-0.5~20110427 from kernel-ppa , and everything is running smoothly.

Any Ubuntu developers care to track down which mesa commit(s) should be backported to Natty? Would be great if I could go back to stable Natty packages.
