Hi,
Since updating my snapshot machine last night, I'm seeing the folloing.
This is with one external monitor attached through the dock
(DisplayPort). The "timed out" lines appear when X starts and halt it
for a few minutes. Once X does come up, the error no longer appears. The
last line ("FIFO underrun") appeared about two minutes later during
regular operation.

Find full dmesg attached. I'm also attaching output from a program I
have lying around that dumps various drm info, especially the
monitor/output topology.*
Regards,
pesco
* It currently errors out on a GETPROPBLOB ioctl somewhere late, which
I would have to investigate, so the output is truncated - but the
important info should be there.
