I have an Atom-based D945GCLF2, which I use as a MythTV frontend. I use the built-in S-video output. Xorg 7.4 with Intel driver 2.7.1 (Debian package version 2:2.7.1-1). I ran "xset dpms force off" to blank the display, and this worked with no activity on the display (at the main menu of the MythTV frontend). However, running this with a video playing led to several messages like this: [drm:i915_wait_irq] *ERROR* EBUSY -- rec: 5645 emitted: 5648 A few seconds after those messages appeared, the system locked up completely, requiring a hard reset.
Note that I can consistently reproduce this.
Given that the error message mentions drm, it occurs to me to mention my kernel version: 2.6.26, from Debian stable (package version 2.6.26-15lenny2).
Please attach Xorg.0.log and dmesg, according to http://intellinuxgraphics.org/how_to_report_bug.html. Please also attach "xvinfo" output. Haien, can you reproduce this?

and I also test it with mythtv on our 945g and couldn't reproduce this issue.
Created attachment 26319 [details] Xorg.0.log after X and the MythTV frontend start
Created attachment 26320 [details] dmesg after system boots and starts X Note that the set of three "[drm:i915_getparam] *ERROR* Unknown parameter 5" messages appear when X starts. The second set here appears because I restarted X.

This error means the kernel doesn't support GEM. You need newer kernel >=2.6.28 to resolve this error. Could you try a newer kernel, better the latest one?
please reopen if you could reproduce with kernel >=2.6.30.
