<3>[180030.123002] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... render ring idle [waiting on 9664668, at 9664667], missed IRQ?
I got these every 1.5s.

now I am running 1.11.99.902 without fedora patches, fingers crossed

Daniel, another render ring IRQ miss surfaces!

I suspect we have a further issue, but we can at least fix the render ring IRQ miss and see what remains...

Please test the for-nkalkhof branch available in the kernel git repo at:

Thats's expected, you need to checkout my branch:

git checkout origin/for-nkalkhof

So it was the kernel, first I thought I was cloning libdrm, no wonder it was so humongous ;)

Isn't there a spinoff of the missed-irqs patch for 3.0.x kernel?
I don't really have time to start tinkering with this nkalkhof kernel..  maybe I just wait till the fixes land into 3.2.stable..

Currently that patch will land earliest in 3.4, so trying out that git kernel is highly advised if you don't want to wait a few months for a possible fix ...

OK, thanks, I guess I have to start using it if I start getting serious hangs (requiring reboot) more regularly (>2 times a week).

ok I had to sysrq-k three times inside 24h, so I compiled -nkalkhof kernel.
it is not very stable, either.  it crashed the instant I ran mplayer -fs -vo gl some.mkv.

The residual bug is bug 44364, so retitling as appropriate to separate the issues.

now with 7½ days uptime it has had only one more GPU hang, not bad.

but I am wondering how often do you merge the linus stable to for-nkalkhof..?

this with mesa df5963c25641a7c3a4bbfcb81cc3dc771581590e and nkalkhof kernel

Which is still your *mesa* bug 44364, this bug is tracking the occurrence of the IRQ miss on SNB which does has a patch going in 3.4.

A patch referencing this bug report has been merged in Linux v3.4-rc1:

commit 99ffa1629d737295e569267cf5940758139f9ddb
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Wed Jan 25 14:04:00 2012 +0100

    drm/i915: enable forcewake voodoo also for gen6

Patch has landed, closing this bug. The residual gpu hang looks like a separate mesa issue, missed IRQs seem to be gone for good. If they pop up again, please reopen.
