DPCD went mad it seems. I wonder if this monitor might occasionally need the
dummy read wakeup trick we have for the HP ZR24w.

I see we also managed to read a corrupted EDID from this guy at some point:
[   17.753230] i915 0000:00:02.0: DP-1: EDID is invalid:

Also other corrupted junk:

Hmm. I wonder what is going on with GMBUS. Did we break it recently or
was it already broken?

Same corrupted DPCD stuff.
