Hi!

I have installed a hwe kernel in my kubuntu 20.04. I needed to do that
because the standard kernel caused random freezes.
It has been working pretty well for long time even after changing a
couple of kernel versions, the last working one being 5.13.0.
Now there came another version 5.15.0. After a normal update and reboot
the system hangs at "Loading initial ramdisk"!
Booting 5.13.0 still works fine.

I have tried to rebuild initramfs, reinstall the nvidia drivers,
update-grub. No success :-(

Any suggestions?

Thanks
Paulo

Seems to be a problem with that kernel. What nvidia GPU and what driver?
Does it also happen with nouveau?

Was "Loading initial ramdisk" followed by the LUKS prompt?

I would run "memtest" and make sure the RAM is good.

The MODULES=dep procedure, as described in your second link, fixed the
problem :-)
THANK YOU.
