Yes, the -EINVAL error is strange. It is returned also in kernel/module/main.c on few locations. But neither of them looks like a good candidate.
OK I updated to next-20230119 and I don't see the issue now. Odd. It could have been an issue with next-20221207 which I was on before.
I'll run some more test and if nothing fails I'll send the fix to Linux for rc5.
Jeesh it just occured to me the difference, which I'll have to test next, for next-20221207 I had enabled module compression on kdevops with zstd.
You can see the issues on kdevops git log with that... and I finally disabled it and the kmod test issue is gone. So it could be that but I just am ending my day so will check tomorrow if that was it. But if someone else beats me then great.
With kdevops it should be a matter of just enabling zstd as I just bumped support for next-20230119 and that has module decompression disabled.
So indeed, my suspcions were correct. There is one bug with compression on debian:
- gzip compressed modules don't end up in the initramfs
There is a generic upstream kmod bug:
- modprobe --show-depends won't grok compressed modules so initramfs tools that use this as Debian likely are not getting module dependencies installed in their initramfs
are you sure you have the relevant compression setting enabled in kmod?
$ kmod --version kmod version 30 +ZSTD +XZ +ZLIB +LIBCRYPTO -EXPERIMENTAL
Debian has:
kmod version 30 +ZSTD +XZ -ZLIB +LIBCRYPTO -EXPERIMENTAL
^ so... mind the minus :). It doesn't support zlib.
Change your kernel config to either compress the modules as xz or zstd.

Perhaps this was related to the above gzip issue in debian then.
I'm hoping will have a bit more time than me to verify.
