--- Comment #6 from Simon Kitching skitching@apache.org 2012-09-16 07:20:29 UTC --- Most of the discussion on this issue has been going on at bug 54129 and bug 51344.
A patch has recently been merged into Linus' tree for 3.6-rc5+:
commit f492c171a38d77fc13a8998a0721f2da50835224 Author: Christian König deathsimple@vodafone.de Date: Thu Sep 13 10:33:47 2012 +0200
drm/radeon: make 64bit fences more robust v3
This fixes the issue, so I'll close this bug as fixed. Thanks to Christian,Alex,Tony,Jerome.
Just a minor note: perhaps a comment in the patch would have been useful, to explain why the extra ORs and comparisons are needed - so the next cleanup doesn't take them out again?
