hint at a problem in the system's design. 00:03.0 is the parent bridge
of 02:00.0 (and from what I can tell that's the only device behind that
bridge), and hence the above messages can only reasonably have
their origin at the passed through VGA device.

Okay, I did a bisection and was not able to correlate the above error message with the problem I'm seeing. Not saying it's not related, but I had plenty of successful test runs in the presence of that error.

Took me about a week (sometimes it takes as much as 6 hours to produce the error), but bisect narrowed it down to this commit:
