Bug#1032003: nvidia-driver: nvidia driver fails to load after upgrade 520.56.06-2 -> 525.85.12-1 in debian testing

[Fluorescent Flux]

This seems to be the key line:


Feb 26 17:48:36 aw nvidia-persistenced[681]: device 0000:01:00.0 - failed to
open.

However, search shows that other cases with this line involved usually
have some extra info before the line is logged. In my case, there is
nothing, and I am at loss how to debug issues like this. So, any help
is appreciated.
