Thanks. I'm running through those now, and it seems like I'm doing
closer to what the CI logs show [1], but I'm still not reproducing on my
GLK. (I've now managed to run it with drm-tip; still no luck.)

So far, now I've managed to just reproduced *different* known problems:

https://lore.kernel.org/all/Y2WfpLbX1SeDtk+7@google.com/

But after working around those, I run without any similar lockup
failures.

I might poke around some more next week, but I've probably spent more
time than reasonable on this already.

Anyway, thanks for the help!

Regards,
Brian

[1] For one, I've run through a test list, in order, based on this:
