Are you quite sure this is actually the old, working, initramfs?  (What
is that a xymlink to?)

I added an extra line to the boot menu in the hope that things can remain working).

The current version of initramfs-tools (0.148.1) has a rewritten
unmkinitramfs and an autopkgtest script for it.  But the implementation
in 0.147 also passes all test cases except those where all component
archives are uncompressed, which is not something initramfs-tools ever
generated.

Does the new implementation of unmkinitramfs work any better on the
working initramfs image?

That at least doesn't fail. Yes, it seems to extract the content.

If not, can you upload the image somewhere for me to inspect?

Given the answer above, do you still want me to do this?
