As reported upstream, when I used the drm-tip kernel I didn't see the FIFO
error message in the logs again (but still had random power downs).
I'm running the mainline kernel 4.15.0-041500rc8-generic and also don't see any
of the described issues anymore (although I still have 1-2 random
So I was just able to reproduce the shut-down issue with the kernel
4.14.0-041400rc8-generic and the debugging flags enabled.
I submitted a kern.log to the upstream bug report.

I didn't know docking stations had firmwares up until now. Is there a way to

Regarding your other questions:
1) The issues have not happened without locking so far. Everything works
smoothly when I don't lock (so that's why my workaround is to not lock the
screen when I'm only away for short, although it's against company policies...)
2) When docked in the docking

So I used the kernel at drm-intel-nightly/current/

attach the requested files.
