I have a GK107 with a different but likely related problem, and with identical
timing: upgrade from 6.6.x to 6.7.x:
https://gitlab.freedesktop.org/drm/nouveau/-/issues/385
I've seen recently other bugs with old NVidias, plus another I filed:
https://gitlab.freedesktop.org/drm/nouveau/-/issues/214
These are making me suspect support for these oldies is disintegrating as kernel
versions increment. When booted to a failing kernel, do you see any of the same
drm and/or DDC errors in dmesg that you can see in the #385 bug? It might be worth
trying my workaround of 2025-03-08 comment in #385.
