Distro bug: https://bugs.archlinux.org/task/37085
Hardware is Intel 945GM
Can you please test with the latest drm-intel-fixes git branch from http://cgit.freedesktop.org/~danvet/drm-intel/ If the issue persists please boot with drm.debug=0xe, reproduce the WARN and then attach the complete dmesg to this bug report.

I tried with 3.11.1 and that one's still good. I don't know if I can get a kernel built but might give a try later and can't reboot the machine at the moment anyhow. Don't you think https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=cc0ffca95bf3e8cd393327c444c5bf4493deda90 is at fault?
I can confirm the bug on my i7-3770k (onboard HD 4000). If I revert the commit that Carsten linked in comment #4, I get no such error in dmesg.

Neglected to mention my box is x86_64 so I changed the tag on the bug (op's was i686).
Jon: You have a different bug, please separate a new report for it. When you do so please boot with drm.debug=0xe and attach the complete dmesg. Carsten: Strange that the regression is from 3.11.1 to .2. But without the drm.debug=0xe dmesg I can't really tell much more.
@Daniel - I rebooted with the debug flag bug could not replicate the error?! Removing the debug flag as well, booted into a non-error state. This is using the stock kernel (i.e. without reverting that commit).

In general _please_ file new bug reports, it's much easier for us to mark a bug as a duplicate than to untangle a maze of me-too reports that effectively are all different bug reports. I know that bugzilla gives you a neat list of possible dupes, but ignoring that is usually the best option. Of course if an upstream dev told you (on irc or so) that there's a bug report already that's different.

I've somehow lost the cc: stable tag. Just sent a mail to greg, so this should get fixed asap.
Confirming Comment 19, issue NOT fixed by 3.11.3
