Subject: Commit ecff665f5e3f (drm/ttm: make ttm reservation calls...) causes system hang on Radeon RS780
Date: Wed, 10 Jul 2013 11:22:11 +0200 [thread overview]
Message-ID: <20130710092211.GB356@x4> (raw)
By simply copy/pasting a big document under LibreOffice my system hangs
itself up. Only a hard reset gets it working again.
see also: https://bugs.freedesktop.org/show_bug.cgi?id=66551
I've bisected the issue to:
commit ecff665f5e3f1c6909353e00b9420e45ae23d995

drm/ttm: make ttm reservation calls behave like reservation calls
This commit converts the source of the val_seq counter to
the ww_mutex api. The reservation objects are converted later,
because there is still a lockdep splat in nouveau that has to
resolved first.
