I am trying to update the kernel of Ubuntu from 5.8.0-50-generic to 5.9.1-rt20 (because there was no patches for 5.8.*, not sure why), but the system freezes after Loading initial ramdisk. Same thing in recover mode.

The computer is Fujitsu celsius M770power. OS is Ubuntu 20.04 LTS. dis_ucode_ldr option is set, BIOS is updated (popular fixes on the Internet).

I know it is not very detailed, but I am ready to provide all needed logs. Thank you.

P.S. Ubuntu was not my choice and I can't switch to other distro.

Grub's "initrd" could not load ramdisk image. The problem was solved by installing and configurating of systemd-boot.
