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.
