--- Comment #4 from Andreas Bombe <aeb at debian.org> ---
While bisecting I noticed that CONFIG_DEBUG_WW_MUTEX_SLOWPATH was introduced
and that I had it enabled. Since that potentially introduces additional
-EDEADLK I suspected that check.

Turns out that check was buggy, the fix 85f489612 "mutex: Fix w/w mutex
deadlock injection" was merged since I posted this bug and the commit even
mentions explicitly that the bug caused spurious GPU lockups on radeon. The
problem appears to be gone with this fix.
