Subject: [3.7-rc5/rc6 regression] "drm/nvc0/disp: fix regression in vblank semaphore release" broke nouveau driver and mplayer
Date: Sat, 17 Nov 2012 20:35:18 +0100 [thread overview]
Message-ID: <20647.59126.898316.299551@pilspetsen.it.uu.se> (raw)
mplayer worked fine on my Dell Latitude E6510 (nVidia GT218 [NVS 3100M] graphics)
up to and including kernel 3.7-rc4. However, with 3.7-rc5 or -rc6, any attempt to
run mplayer just blanks the screen, shows some stray white pixels in the upper left
corner, kills the X server, and spews the following errors from the kernel:

The error is 100% repeatable.
git bisect identified the following culprit:

I've confirmed that reverting this from -rc5 and -rc6 allows mplayer to work again.
User-space is Fedora 15 x86_64 w/ final updates, plus mplayer-1.0-0.129.20110917svn from rpmfusion.
There are no binary-only or otherwise out-of-tree kernel or X drivers anywhere on the machine.
Please revert or fix this breakage before kernel 3.7.0 final.
