I am trying to get libavg (http://libavg.de) running on my acer timeline 1810tz notebook, but a test script (src/test/Test.py) reproducibly freezes the X session (i can move the cursor, but cannnot interact with anything) and i am unable to restart it (tried SAK and xdm restart, but i only get a black screen with a mouse cursor). I can still switch to VT's, so i could collect dmesg, xorg log and run intel_gpu_dump (I also included a dump taken directly before the program start)

System environment: 
-- chipset: GM45
-- system architecture: 64-bit dual-core
-- xf86-video-intel: xserver-xorg-video-intel 2:2.9.1-1                   
-- xserver: xserver-xorg 1:7.4+4 
-- mesa: 7.6
-- libdrm: 2.4.15-1
-- kernel: 2.6.32-rc8-amd64 (debian built)
-- Linux distribution: debian testing
-- Machine or mobo model: acer timeline 1810tz
-- Display connector: lvds + vga

KMS is activated. With a .31 kernel, the freeze/crash also occurs and i can't even switch to VTs.

Thanks in advance for your help!

I tried to test this with libavg 1.5.0 built from source (since Test.py isn't included in debian packages), but it segfaults somewhere in boost-python when starting.  Could you test with current Mesa+kernel+2D driver, since we've fixed a lot of GPU hangs since Mesa 7.6.

(clear NEEDINFO when replying)

Tentatively marking this fixed, unless we get a response otherwise.
