#74120 — Bug#1003210: Module loading also fails on boot

I'm getting very similar errors on boot, when using an encrypted root
file system on LVM. Because it can't load the necessary modules, the
system does not allow me to enter the password to unlock my drive,
making the system unusable unless I boot an older kernel.

Output of lsblk:

Part of the boot log. Other messages with different values for
"bits_offset" and "type_id" also show up, probably one for each module
that's trying to load.

see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=998716 for more
info.

the workaround: ensure the booted kernel and the on-disk kernel modules
are from the same build: either reboot (possibly needs to regenerate
initrd first) or downgrade the on-disk kernel to the booted version.

TL;DRL: Debian either needs to start bumping ABI for every upload, or
hard-disable generating split BTF info for kernel modules

I was reluctant to reboot because the other person couldn't open their 
root disk anymore, but for me it started up fine, and now I can load 
modules again. Thank you!

I'm seeing BFP issues, similar to those reported here:
  https://bugs.debian.org/1003210

except for the virtio_net module. Checking /var/lib/dpkg/status, it
looks like we have kernel-image from 5.19.11-1 and nic-modules from
5.19.11-1+b1, which would mean kernel and modules from a different
build, which was flagged in #1003210 as possibly problematic.

Looping in kernel maintainers to get some input, and debian-cd for
information given the way testing images are built…


Cheers,
