After modprobe failed, is there any output in the kernel log (dmesg)? Do you get more helpfu output whe using 'modprobe -v' to load the module?
What does happen if you manually try to load it bypassing the config file: 'modprobe -i -v nvidia-current-peermem' See enclosed. Next weekend with the next bookworm point release we will switch to the 535 driver series in bookworm. Packages are already available in stable-proposed-updates. Please try that new version, and if the problem persists, we will dig deeper. I will try that and get back to you.
