I have a similar problem with NVidia on kernel 6.18; see 1254882 – Kernel crashing with NVidia binary drivers after update to 6.18.0-1.0.2.
I checked again just half an hour ago, and AFAICS there is now a newer nvidia-open-driver-G06-signed-kmp-meta-580; I had kernel 6.17.9 with nvidia-open-driver-G06-signed-kmp-default-580.105.08_k6.17.9_1.0.2.sr20251106-2.1.6.4.sr20251106.x86_64 (notice the k6.17.9 in the name which probably means “for kernel 6.17.9”), and now, since 2025-12-11 (Thursday), there is a newer nvidia-driver-G06-kmp-default-580.119.02_k6.18.0_1-43.1.x86_64.rpm (notice k6.18.0) at the NVidia repo.
I tried a dup with myrlyn, but it wanted to downgrade a number of nvidia packages to V570 (from my installed 580), so I aborted the whole thing.
Maybe we simply need to wait for the NVidia packages to be updated; right now something seems to be in an inconsistent state.
You could try to downgrade your kernel to the latest 6.17; that might fix your current problem. If it works, lock kernel-default for now and let’s wait for a few days; NVidia together with the kernel maintainers will probably sort that whole thing out.
