Based on my meager comprehension of syslog traces, it looks to me like this is a problem with fglrx. I found somebody at the arch forums with the same problem, seems to be upstream with amd. I will see if rolling back to a former kernel will work, and if that doe4sn't work I will try the opensource driver.

Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of the introduction of a regression, and when this regression was introduced.

This happened after a hardware upgrade involving new motherboard, new amd a10 processor. Had to switch from nvidia binary driver and installed fglrx and amdcccle. Problem stopped when I upgraded to the experimental fglrx, though that brought in a host of other issues.
