Not sure how severe it is but I encountered https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=948257 after today's full upgrade.

Confirmed here!

...
Control: severity -1 serious

raising the severity in case there can be a real major system breakage
(not tested) and also because of the huge number of errors, which can
hide important information (other errors...).

It looks like connected with https://lore.kernel.org/linux-modules/CAKi4VA+QrgGNWSKwZx5NFQWtFdF_M=6_V4_LrV7dEhqvncePdw@mail.gmail.com/T/#m777690a71d45cd7c4544edf721cdfb50d3ded8ca

my lack of deeper kernel/C knowledge does not allow me to judge if this error is indeed critical or not (it might be just lack of this additional info about builtin modules)

I recommend to be patient and wait with d-u/full-upgrade till it is fixed!

[paxmark2]

I had quite a few error messages yesterday via kmod apt full-upgrade in Deb Sid 386 with wayland i3w.  Will see how it goes.  Time to retire the old atom netbook anyway.

That "Bug" is not a bug but a bug!?
More an error, it is spitting out a huge ton of an error message that has to be fixed,
so far I understand.

Printing spurious error messages is a bug, and we will fix it (whether
in kmod or in initramfs-tools, is to be decided).

But since (so far as I know) there hasn't been any regression in the
functioning of the resulting initramfs, the bug doesn't need to be
fixed right this instant.
