I see this error randomly with different games. Good reproducable with minecraft (appears at the first minutes of gameplay). radeon: Failed to allocate a buffer: radeon: size : 4096 bytes radeon: alignment : 4096 bytes radeon: domains : 2 This shows up in dmesg: Also (don't know if that is related or if I should open a new report for it) I randomly get a similar error.

possibly a duplicate of bug 45018.
I think Alex was right. This seems to be fixed in the newest git version of Mesa (which includes patches from Michel Dänzer (comment #119 at bug 45018)).
