Booting issues with kernel 5.14.0-1

Observed that clients/servers with Ryzen/AMD hardware has issues to boot with kernel version 5.14.0-1

During the boot, I got the following:

Loading Linux 5.14.0-1-amd64 ...
Loading initial ramdisk ...

and there it stops.

I have tried to change the quite kernel parameter to ignore_loglevel and placed at the end of the line the number 3 but this did not helped or showed any errors at all

Booting into the old kernel 5.10.0-8 instead of 5.14.0-1 worked fine.

To “quick solve” the issue, you can add the following kernel parameter mem_encrypt=off to the grub config

For example like this:

GRUB_CMD_LINE_DEFAULT="quite acpi_backlight=vendor mem_encrypt=off"
