Does the issue still occur with radeon KMS disabled? I suspect this may be related to similar problems other users are having, the common denominator in those cases seems to be Radeon video with KMS enabled by default. I have linked the bug reports upstream on those issues, but it would be worthwhile to see if this is related.
