Checking dmesg I see the request to create a post here along with the GPU hang file. Running i3-3240 on Ubuntu 13.10 x64 , play back in XBMC alpha 10 with SOFTWARE playback.

I can reproduce this quite consistently. I noticed it yester when I watched a movie, a "freeze" came every few minutes (just the video, HDMI audio was fine). It still happens today, even after reboot.

After going to 3.13.0 I see some errors in dmesg (e.g. "factorial" or "conftest") poping up, even running a 3.11.10 kernel doesn't change this. Not sure, maybe something is wrong with Linux now or my hardware. It worked perfectly till I went to 3.13.0... I'll run a memtest etc. and will update here asap.
