Would you mind posting the full log rather than filtering/grepping through? Some of the backtrace has gone missing, and it'd be good to see other events in the system just for reference. Thanks!
Created attachment 123622 [details] dmesg 4.5.2 It's extracted from journalctl, so instead of nouveau I grepped it for kernel. I hope it's more complete this way.
Hi, do you still need more info? I'd be happy to provide it.
Sounds like issue with multi-threading OpenGL support in nouveau, see #98039
