I currently experience frequent CPU hangs. These started some time ago; I'm unsure whether they came about by a driver, Xorg, or kernel update. They happen without doing anything specific.
- Xorg 1.13.1
- xf86-video-intel: 2.20.19
- Linux kernel: 3.6.11
- Core i5-2400 (model 42, stepping 7)
- CPU-integrated Intel graphics
Attaching a sample error state.
Note: I've intermittently set the following kernel parameters, without any apparent impact on the issue's occurrence:
Can you please reteste with latest 3.8-rc4 kernel? We've fixed a few gpu hang bugs on snb just recently, so would be good to rule those out.
*** This bug has been marked as a duplicate of bug 54226 ***
I've meanwhile upgraded the kernel to 3.8.0-rc4 (as has been asked), and xf86-video-intel to a git revision of some time yesterday (commit 778dba90). I still get hangs, but these can be recovered by switching to the console and back to X.
Attaching a new error state.
