dmesg from 3.12-rc1 with drm debug

There is a seemingly harmless WARNING on every bootup on my PC with DP monitor. It appeared between 3.6 and 3.7, first reported on LKML https://lkml.org/lkml/2012/11/12/343 in Nov 2012. Later it was added to a bugzilla bug https://bugzilla.kernel.org/show_bug.cgi?id=52061 where the old dmesgs from 3.6 and 3.7 are still present. This bug came out to be something different so I am resubmitting it as a separate bug on Ironlake.

I retested it with 3.11 and 3.12-rc1, it is still there, dmesg with drm debug from 3.12-rc1-00101-ged24fee is attached.

Already tracked in the fdo bz at: https://bugs.freedesktop.org/show_bug.cgi?id=54687

I guess we can keep this one here around anyway. For the actual bug we've unfortunately not grown any clue, but it really shouldn't happen. Hence why we're keeping the WARN in there as a remainder.

IMO no reason to keep this open. Let's track this at fdo. Please reopen if this turns out to be a different bug after all.
