Yeah, you had mentioned that. >> Anyway: could you try to bisect the problem as described in >> https://docs.kernel.org/admin-guide/verify-bugs-and-bisect-regressions.html > Will do. > > Thank you for your reply! 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.
