*ERROR* Hangcheck timer elapsed

Hi,

I'm using intel sandybridge graphics (xf86-video-intel 2.15.0) with linux 2.6.38.4. Whenever I run app that requires OpenGL(e.g. glxgears), I GPU hangs about every 3 seconds.
dmesg shows:

[ 58.693676] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 6200, at 6200], missed IRQ?

I googled and didn't find anything useful. I thought is was a bug and should be fixed in the future until today when I tried Ubuntu 11.04.
When I boot to Ubuntu 11.04, glxgears ran perfectly, no GPU hangs no strange white striped or flicker (https://bugs.archlinux.org/task/23771)
I noticed that ubuntu is using kernel 2.6.38 and xf86-video-intel 2.14.0.
Anyone knows how come this can happen? or how to fix this?
Thanks

Same error here... I temporarily solved this by installing kernel26-mainline (2.6.39-RC5) from AUR, but the error reappeared after updating to 2.6.39-1

Those errors can be dealt with by downgrading / installing some other version of e.g. the drivers from AUR.
Older version of Arch software is available from http://arm.konnichi.com/search/

Known problem, see http://www.phoronix.com/scan.php?page=a … orks&num=1

It seems like this was fixed for some systems in 2.6.39 and for other systems it made it worse. On my 2.6.38 system I have those hangs as well, haven't tried 2.6.39 yet. I hope this is gonna be fixed in 2.6.40 for everybody...

I was about to post a new topic about this, but it seems I don't need to. I encountered this problem last night when I was converting my old server to a media system. This is what lspci says about my server's GPU:

00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)

Going to install kernel26-lts and see if that helps any
