So I have installed 4.12-rc6 from drm-tip, and this is what the kern.log entry
looks like now for me:

enabled.

*ERROR* DC state mismatch (0x0 -> 0x2)

The most frustrating thing that it seems to be only happening when I'm away,
although I don't have a suspend timeout set. Plus it only seems to be happening
when I use an external monitor via a thunderbolt port.

Can I provide any more details here?
