--- Comment #19 from Daniel Vetter <daniel at ffwll.ch> ---
Ok, we need to split this bug up, there's way too many different bugs here.
>From the bug filing BKMs:

- if the WARNING in dmesg is different, it's a different bug. Special case: for
pipe_config mismatch you need to look at the *ERROR* right above. We seem to
have mismatches here in has_infoframes (tracked in bug #93119),
dpll_hw_state.cfgcr1, base.adjusted_mode.crtc_clock and port_clock. The three
clock mismatches are probably related.

- igt failure below seems to be another issue again. Probably needs a separate
bug.

- once we have split out all the bugs per BKM please add an entry here linking
to all the new ones and close this one as invalid/superseeded. All the new bugs
should be priority=highest since they're BAT failures.

Thanks, Daniel
