Hard to say without seeing a backtrace, but I'll bet this is the bug fixed by commit 1d465178fbab77a9c0e830ea8c47bf61735def71 "radeon: fix GTT writing space check", but there's not enough info on hand to be absolutely certain.
I'm uploading libdrm 2.4.13 which contains this change. Reopen the bug if you can reproduce the bug on that version of libdrm.
