Description of problem: Upon booting the rawhide kernel, I have a perfectly stable X image... as long as the screen is not updating. On any update, the image jumps about 500 pixels to the right for a tenth of second before snapping back. It's pretty trippy. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.6.1.901-1.fc11.x86_64 xorg-x11-drv-intel-2.7.0-7.fc11.x86_64 kernel-2.6.31-0.94.rc4.fc12.x86_64 How reproducible: Once is enough Steps to Reproduce: 1. Install new kernel. 2. Reboot. Actual results: Chaos on any screen updates. Expected results: Happy X. Additional info: 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) [notting@nostromo: ~]$ xrandr Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 4096 x 4096 VGA1 disconnected (normal left inverted right x axis y axis) LVDS1 connected 1400x1050+0+0 (normal left inverted right x axis y axis) 287mm x 215mm 1400x1050 60.0*+ 50.0 DVI1 disconnected (normal left inverted right x axis y axis)
Hmm. This was just before I added the PM code, so I think this is Kristian's problem rather than mine.
Backing down to 2.6.30-6.fc12 works. Haven't tried anything else in between yet.

Persists in .118.
krh suggested that this could be an issue with the "fifo watermark" that Jesse Barnes @ Intel is trying to fix.
kernel-2.6.31-0.123.rc5.git2.fc12 or later includes jesse's watermark fixes. Give that a try?
0.122.rc5 WFM.
