Meelis Roos it looks like you have a different system (ironlake vs. the
sandybridge of the original reporter), so rather likely that you also have a
different bug. The WARN is simply a paranoid check whether the hw works as it
should, which can (but not necessarily must) lead to display issues.

Kalin, the wait_pipe_off timed out WARN on ilk is typical for external DP
monitors (when disabling the screen, i.e. dpms, xrandr --off or unplugging the
cable). Would this match up with when you can reproduce these WARNs and when
not?
