After running 3 days with radeon.msi=0 it seems the hang is gone. Did not suffer this problem until now.

Okay, so I'm reassigning this to the kernel driver for now, though this might just be a duplicate of another MSI related report here or in the kernel bugzilla.

"EXAPixmaps" is "off" because i see many artifacts sometimes on the screen otherwise - maybe its the greedy option, did not test both exclusive.

Option "MigrationHeuristic" has no effect with KMS. Disabling EXAPixmaps probably just avoids the problem because it prevents hardware acceleration in most cases. The corruption looks like bug 47266, would be nice if somebody could find a working driver snapshot and bisect.
