Comment 1 Jani Saarinen 2018-12-17 20:01:55 UTC
This should be fixed by: https://patchwork.freedesktop.org/series/54017/
Comment 2 Jani Saarinen 2018-12-17 20:05:42 UTC
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.
