Daniel, I have noticed these warnings on 3.12-rc1, did not go away on
I see it only on EeePC with i915,not on ThinkPad with Radeon.
It is a 32-bit kernel with overlayfs and TuxOnIce patches, so not
clean, however same config and patches on 3.11 do not show these issues.
No,sorry, did not have time to investigate further or bisect.If you have
quick test in mind - I will try ;-)

a) Please always cc: relevant mailing lists, not just your maintainer.
b) Please retest with latest drm-intel-fixes from
c) If that doesn't help please boot with drm.debug=0xe, reproduce the
issue once and attach the complete dmesg. Please make sure that it
contains everything from boot-up to the WARN.

Thanks, Daniel

Pull request is already out and patch is cc: stable, so should show up

Warnings are gone with this patch (and other 4 patches since 3.2.12-rc2 from drm tree).

Thanks, Woody
