Very slow reboot

When I reboot system this do is very slow
Startup finished in 6.811s (firmware) + 2.776s (loader) + 2.394s (kernel) + 1min 31.740s (initrd) + 1min 32.100s (userspace) = 3min 15.824s reached after 1min 32.100s in userspace.

as we see I get every time message A start job is running for Load Kernel Modules

Can we see inxi -Fxxxz?

If you are using nvidia drivers, add the ibt=off option to the kernel commandline.

It looks like nvidia. If you have the proprietary nvidia drivers installed, make the change described above with ibt=off

where I need to set this parameter?

Are you using grub or systemd-boot?


Add that to the end of the line /etc/kernel/cmdline and the run sudo reinstall-kernels

Thank you very much is solved.
Why is that problem happened?

It is a compatibility issue with the nvidia drivers. 12th gen and later Intel CPUs implemented a feature that the nvidia drivers don’t support properly. You need to disable it to properly use the proprietary drivers.


I had the same problem, the system won’t boot up until 2min passed => fixed with ibt=off.
But I have one question: When the fix will be included in Driver/Kernel or whatever, we need to revert the ibt=off?

The driver is proprietary so there is no way to know unless nvidia announces it. It will be fixed when nvidia fixes it. :person_shrugging:
