As @andrum99 indicates, compare with a new installation. In the more than 20 years that I use Linux I have done that several times unfortunately. It costs time, but after all we on this forum also don't know anymore, except maybe that you still need to search better where that 'serial saved-state' comes from.
Note that new install for me does not mean getting an extra SD-card or so. I do the installation on an extra partition. I save the contents of the boot FATpartition in the specific matching root partition for the current/faulty/old OS. That also forces you to check/refresh/overwrite the files there. Maybe a 512byte -sector in some file is corrupt, we don't know.
And check/regenerate your initrd. Does the one in /boot match the one on the bootFAT (/boot/firmware)? Maybe extract it and see what scripts are run at boottime from there. Search internet how to do such an extract.
