mhh, this shouldn't happen and the accesses below are probably related
to this. Mind sharing your complete dmesg via a pastebin site or just
go ahead and file a bug at
https://gitlab.freedesktop.org/drm/nouveau/-/issues ?

I assume you are on the newest kernel and everything? I will check if
I can reproduce it on the fermi I've got here, but could be something
specific to your GPU.
