his nvidia is working on the 5.15 kernel, so its probably the ibt bug:
kate /etc/default/grub
and inside this line: GRUB_CMDLINE_LINUX_DEFAULT inside the quotes add this parameter:
ibt=off
dont remove anything from there, just add it to existing parameters, save the file, update grub:
sudo update-grub
now you should be able to use nvidia also on newer kernels…
