- Were there any problems with the system after upgrading?

System fails to boot after upgrade - hangs after loading initramfs.

On enabling debug within grub, the hang occurs at:

kern/verifiers.c:88: file: /boot/initrd.img-6.1.0-8-amd64 type: 131076
kern/verifiers.c:103: trying verifier pgp
kern/verifiers.c:103: trying verifier tpm


Can be worked around with:

GRUB_TERMINAL=console

... with this setting in place the system boots as expected.
