With a tree that is close to 3.15 final I'm regularly seeing the following on my EeePC 900 when starting ioquake3:

Hm, I've thought we've fixed that by now. Alas, no :(
Can you please add drm.debug=0xe to your kernel cmdline, reproduce the issue and attach the entire dmesg? Please make sure it contains everything since boot-up so that we can reconstruct the state properly (might need to grab it from logfiles if dmesg is cut off).
Also, do you have any ideas when you reproduce this? Anything that changes the lvds output could be relevant ... -Daniel

Doing xrandr -s 800x600 xrandr -s 0
was enough to provoke the messages in the attached log.
(resending because Daniel was dropped from the reply list - I don't know why)

Not in the resend and I didn't seem to receive your original mail somehow at all. Can you please resend.

Ok, makes sense. Smells a bit like leftover pfit state. Can you please also try latest drm-intel-nightly?
Thanks, Daniel

Downloadable from http://sucs.org/~sits/test/eeepc-900/dmesg-20140611 .
By the way, Mutt seems to be becoming upset when I group reply to your mails. I think it's because your address is in both the To: and the Cc: fields....

The previous log is from drm-intel-nightly but there seem to be more warnings in it rather than less...
