So our modeset sequence is still crap. Was this already present or a new
problem?
Do you have this in your tree?
commit 08aff3fe26ae7a0d6f302ac2e1b7e2eb9933cd42

drm/i915: Move DP port disable to post_disable for pch platforms
If yes, try reverting. The funy thing is that it fixes a pipe_off
timeout on my ILK and didn't cause any harm on my IVB, but perhaps
your IVB is more special than mine. It also matches the modeset
sequence in the docs better, but perhaps it's still not close enough,
or the docs are just plain wrong.
