Created attachment 24448 [details] xorg.conf I've just gotten about five crashes of the X server, each with the backtrace: 0: X(xorg_backtrace+0x26) [0x4ea426] 1: X(xf86SigHandler+0x39) [0x47e0f9] 2: /lib/libc.so.6 [0x7f4d381e7040] 3: /usr/lib/libdrm_intel.so.1(drm_intel_bo_unpin+0) [0x7f4d3705db70] 4: /usr/lib64/xorg/modules/drivers//intel_drv.so [0x7f4d3729cb89] 5: /usr/lib64/xorg/modules/drivers//intel_drv.so(i830_crtc_dpms_video+0x4a) [0x7f4d3729cc0a] 6: /usr/lib64/xorg/modules/drivers//intel_drv.so [0x7f4d37289fa1] 7: X(xf86DPMSSet+0x95) [0x4a3805] 8: X(xf86SaveScreen+0x29) [0x4a3fa9] 9: X(dixSaveScreens+0x241) [0x43a2d1] 10: X [0x4e733b] 11: X [0x4e7728] 12: X(WaitForSomething+0x56b) [0x4e7d7b] 13: X(Dispatch+0x7f) [0x449fff] 14: X(main+0x44d) [0x430b2d] 15: /lib/libc.so.6(__libc_start_main+0xe6) [0x7f4d381d25c6] 16: X [0x42ff19] The crashes only seem to happen when I'm not using the X server (probably right when it turns off the monitors): the system seems quite reliable so long as I'm actually using it. But then when I go away, and come back to find the monitors in power-saving mode, often the server has crashed, leaving the keyboard in an unusable state, requiring a reboot via the power button. My setup is: G965 with dual-DVI ADD2 card, driving two monitors. Gentoo Linux xf86-video-intel-2.6.3-r1 libdrm-2.4.5 xorg-server-1.5.3-r5 Linux kernel 2.6.29. (I also tested it with 2.6.28, and got the same crash.)

I'm willing to help debug this one; please let me know what additional information would be desirable.
Some more information: the crashes only seem to occur after the video overlay (Xv adaptor 1) has been used. That is, if I play a video using the video overlay, then later let DPMS activate, the X server crashes on DPMS activation; this seems to happen every time. If I use the textured video adaptor instead, crashes don't seem to happen at all. At least that's the pattern so far.
I think this is fixed upstream already, can you try git master or this patch on top of your 2.6.3 driver? commit 74d0713e002a9781ed00fdd10eb6f75907ae796c Author: Kalev Lember <kalev@smartlink.ee> Date: Fri Mar 20 02:21:41 2009 +0200 Fix VT switch with XV overlay video enabled. drm_intel_bo_unpin() was called with NULL argument.

*** Bug 21025 has been marked as a duplicate of this bug. ***
Works for me but I had to change the top of the patch a little because one part is a little different.
Created attachment 24609 [details] [review] Patch for Ubuntu xserver-xorg-video-intel 2.6.3-ubuntu5
Great, thanks for confirming.
Yes, works for me too (with similarly-changed patch).
Thanks for fixing/pointing out the patch so fast :)
