Description Tomas M. 2010-03-01 05:48:07 UTC

after upgrading to 2.6.33 i decided to test the overlay feature implemented. 

when running with overlay enabled, playing a video usually hangs the system. with this i mean, the screen freezes, video stops playing, but i can still ssh into the box.

after some testing as described in the bug i posted in the kernel bugzilla here: http://bugzilla.kernel.org/show_bug.cgi?id=15389 the conclusion is that the GPU is actually not hung, and that userspace is stalled.

ive already tried backtracing X, but when te freeze happens, X doesnt break execution. 

hardware involved:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS,
943/940GML Express Integrated Graphics Controller (rev 03)


xorg.conf relevant snippet

Section "Device"
    Identifier  "Card0"
    Driver      "intel"
    VendorName  "Intel Corporation"
    BoardName   "Mobile 945GM/GMS, 943/940GML Express Integrated Graphics
Controller"
    BusID       "PCI:0:2:0"
    Option        "XvPreferOverlay" "True"
EndSection

i already fetched a gpu dump which is here: http://bugzilla.kernel.org/attachment.cgi?id=25200

any extra info needed, i will happily provide.

i forgot to mention:


dmesg comes in clean.

Xorg.0.log is clean too.

no error anywhere.

Forward dup'ing.
