Phoronix: 30 Patches To Intel's Linux DRM Driver Published
To the Intel graphics mailing list, Chris Wilson has just published a set of thirty patches to be applied against their DRM tree that will end up being merged for the Linux 2.6.40 kernel. Some of these patches are quite interesting...
Does this patch fix the Hangcheck timer problem?
So does this patch fix the Hangcheck timer issue? I've been getting this message hundreds of times per day on my Natty box (H67 i5-2500K):
[drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle...[continued]
All my attempts to startup an OpenGL game have been fruitless :-(
see this Phoronix article. Solved this issue for me.
Edit /etc/default/grub, add i915.semaphores=1 to GRUB_CMDLINE_LINUX_DEFAULT, run update-grub and reboot.
