Randomly happens in logs. I'm separating all my radeon bugs in to each topic,
if found to be related we can close them in pairs, but for now making sure all
have their own topics so we can get help finding others with the same problems.

Searching this same problem, this was supposed to be fixed for other radeon
hardware a while back, but they still exist in my log. I found a firefox user
with random crashes who reports these also.

My drivers are for RadeonSI, R9 270X 2GB card. Linux kernel 3.17 RC from Oct
6th. I've had these in my logs for a long, long time though.

What does MSC stand for?

Have fun. :)
