dmesg dump after booting to console

I added the parameter 3 to boot to console which resulted in the attached
dmesg_dump (I re-used the last drm-tip kernel I compiled).

After attaching the monitor to the docking station I got a couple of FIFO
underrun messages directly on the console. I took a photo, however, they are
also reported in the dmesg dump.
