3. Suddenly the secondary Nvidia-connected display turns off and X
stops responding to keyboard/mouse input.

I am currently testing v6.6 with the culprit commit reverted.

- v6.6: fails
- v6.6 with the culprit commit reverted: works

See <https://gitlab.freedesktop.org/drm/nouveau/-/issues/180> for full
details including a decoded kernel log.

Not sure about the others, but it's kind of confusing that you update
the issue descriptions all the time and never add a comment to that ticket.

Thank you for the feedback; I will use comments more for future updates there. I didn't know anyone was following that issue (I haven't received any reply from nouveau developers on the nouveau list [1] or on gitlab [2]) so I have tried to keep that issue description succinct and up-to-date for anyone reading it for the first time.

[1]: <https://lists.freedesktop.org/archives/nouveau/2022-September/041001.html>
[2]: But Karol Herbst did add the "regression" label.

Anyway: Nouveau maintainers, could any of you at least comment on this?
Sure, it's the regression is caused by an old commit (6eaa1f3c59a707 was
merged for v5.14-rc7) and reverting it likely is not a option, but it
nevertheless it would be great if this could be solved somehow.

Also if anyone has any ideas about any stress-tests or anything else that I might be able to trigger the crash with, please share.

Thanks,
Owen
