Isn't this dup of https://bugs.freedesktop.org/show_bug.cgi?id=108924?

Yes looks like it. I guess cibug didn't recognized it as such as the dmesg log is oddly missing lines and so it's missing the

intel_dig_port->tc_type == 0

marker. Petri I think is looking into the root cause of the dmesg mangling.
