There was good progress on this undock bug since the report.

HD audio (with PulseAudio always opening the mixer) no longer is a thing that
prevents undocking. And, if I press the Undock button now, undocking completes
successfully. I am going to attach a dmesg with two dock + undock attempts. In
the first attempt, nothing was using the Radeon card, so we only get a
(possibly unrelated) trace related to backlight. In the second attempt, Radeon
was actually used by the X session as an offload sink, but no programs were
running that actually attempted to render GL on the Radeon. So, despite the
traces, there were no user-visible crashes.
