Confirmed! This bug (blt ring idle) seems to be fixed on 2.6.38-11. There are still issues and other GPU hungs though - after 2 seconds of playing sauerbraten in full-screen: [ 54.562391] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...

Thx for the new Kernel AceLan! I tested the x86_64 version on two different Boards. It got a little better I think - bug happens not that frequently imho. But still, if I e.g. press alt-f2 in Unity and start typing I still get lags and dmesg shows: [ 85.166147] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 39358, at 39358], missed IRQ?

@AceLan Kao I think I found the i915 patch, which would fix this bug (along with a lot of other documented i915 fixes): from (http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.39-rc1) commit 36d527deadf7d0c302e3452dde39465e74a65a08 Author: Chris Wilson ch...@chris-wilson.co.uk Date: Sat Mar 19 22:26:49 2011 + drm/i915: Restore missing command flush before interrupt on BLT ring We always skipped flushing the BLT ring if the request flush did not include the RENDER domain. However, this neglects that we try to flush the COMMAND domain after every batch and before the breadcrumb interrupt (to make sure the batch is indeed completed prior to the interrupt firing and so insuring CPU coherency). As a result of the missing flush, incoherency did indeed creep in, most notable when using lots of command buffers and so potentially rewritting an active command buffer (i.e. the GPU was still executing from it even though the following interrupt had already fired and the request/buffer retired). As all ring-flush routines now have the same preconditions, de-duplicate and move those checks up into i915_gem_flush_ring(). Fixes gem_linear_blit.

Ok forget the post above. Seems to have nothing to do with this bug. On Kernel 2.8.38: /sys/module/i915/parameters/semaphores is set to 0 On Kernel 2.8.39: /sys/module/i915/parameters/semaphores is set to 1 if i do the following: sudo -i echo 1 /sys/module/i915/parameters/semaphores The Bug is also gone on 2.8.38 .

Have also tested this on a ASRock H67M-ITX with i3-2100T and i5-2500T. Exact same symptom. I'm pretty sure now all Sandy Bridge internal GPUs are affected, at least with H67 chipset. This looks serious to me as almost all new PCs are sold with Sandy Bridge. Using development Kernel 2.6.39 isn't a good solution for Sandy Bridge owners i guess. Any chance to get the patch from 2.6.39 back in 2.6.38 ?
