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?
