Red Hat Bugzilla – Bug 495004
xorg-x11-drv-intel-220.127.116.112-2.fc11 broke Xv video, corruption/crash
Last modified: 2009-04-13 11:48:24 EDT
The upgrade from OLD to NEW introduced a regression. mplayer outputting xv video in nomodeset mode causes the screen to turn to garbage while the speakers scream noise.
* If compiz is running, the corruption does not happen.
* If "nomodeset" is removed, the corruption does not happen.
* Downgrade to OLD version, the corruption does not happen.

diff between working and broken version
I'm seeing this too. In syslog when X dies on G45/X4500HD:
Apr 8 21:03:32 shadow kernel: [drm:i915_gem_idle] *ERROR* hardware wedged

edged hardware, good luck
Apparently, more than luck is needed as killing X is ineffective and the system must be rebooted. Downgrade to the prior driver works.
When my system crashes here, ssh logins over the network freeze, perhaps indicating that the entire system has crashed.
git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-intel
git checkout origin/2.7
I tried upstream 2.7 branch at commit ec8ef3b2984cef581ea7fa745a76fe6f97a952dd and it does not crash anymore.
Rebased to today's git snapshot, should be resolved in 18.104.22.1682-3.fc11.
