Yeah, you had mentioned that.

np, but stupid me forgot something (sorry): I had opened your dmesg
file, but not looked into it. :-/

I see that it contains a warning from nouveau that might be hinting at
the problem. Then I'd say: go and file a ticket here:
https://gitlab.freedesktop.org/drm/nouveau/-/issues

Please afterwards drop a link to the ticket here please.

But a bisection might still be needed; if you do not get a reply from a
developer withing two or three days, you definitely want to perform one.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
