ubuntu-22.04-live-server-arm64 on M1: error "EFI_RNG_PROTOCOL unavailable"

[StefanS38]

I'm trying to boot ubuntu-22.04-live-server-arm64.iso on my Macbook Pro M1, Parallels Desktop 1.7.2 (23531), but it fails. When removing the quiet flag from the Grub boot command, I'm getting the following error:

EFI stub: Booting Linux Kernel...
EFI stub: EFI_RNG_PROTOCOL unavailable
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services...

The proposed fix in https://kb.parallels.com/128844 cannot be applied, as there is no kernel alternatives to choose from:

setparams 'Try or Install Ubuntu'
        set gfxpayload=keep
        linux /casper/umlinuz quiet ---
        initrd /casper/initrd

Hi, I had the same problem. It turned out that the VM was not allocated enough RAM. I increased from 512MB to 1024MB and now it works..
