Comment 114 for bug 1842320

I upgraded from 22.04.1 to 22.10. Issue returned as /usr/sbin/mkinitramfs was changed to default. Had to follow my previous steps shown after #41 . . . zstd had defaulted to a lower compression value in /usr/sbin/mkinitramfs at 1 instead of 19. I changed line 196 to 19 compression

    zstd) compress="zstd -q -19 -T0" ;;

Instead of

    zstd) compress="zstd -q -1 -T0" ;;

Problem solved from proper chroot and updating grub2 after changing line 196 of /usr/sbin/mkinitramfs for my system.

I can boot normally again and any upgrades to initramfs don't cause this failure.
