Subject: kernel BUG at drivers/gpu/drm/i915/i915_gem.c:2684!
Date: Thu, 29 Jan 2009 10:57:54 +0100 [thread overview]
Message-ID: <c4e36d110901290157q37223327m73db1e85f7699842@mail.gmail.com> (raw)
Hi
I've tried some experiments with UXA acceleration - it mostly appears
to work with fedora rawhide xorg server.
But with kernel (commit e4a7ca29039e615ce13a61b9c6abfb2aa394e9a1)
(just shortly before -rc3)
I'm getting this oops - suspend doesn't work - display stays black,
magicsysrq works.
