I expect to have a machine (with a crazy number of CPUs/devices) available
in a couple of days (1-2), so no need to rush.

The original machine I was able to reproduce with is blocked for a little
bit longer; so I hope the alternative I looked up will similarly trigger the
issue easily.

OK give this a spin:

https://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux.git/log/?h=20230316-module-alloc-opts

Today I am up to here:

https://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux.git/log/?h=20230317-module-alloc-opts

The last patch really would have no justification yet at all unless it
does help your case.

Still waiting on the system (the replacement system I was able to grab
broke ...).

I'll let you know once I succeeded in reproducing + testing your fixes.

Okay, I have a system where I can reproduce.

Should I give

https://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux.git/log/?h=20230319-module-alloc-opts

from yesterday a churn?

Yes please give that a run.

Reproduced with v6.3.0-rc1 (on 1st try)

By reproduced, you mean it fails to boot?

Not able to reproduce with 20230319-module-alloc-opts so far (2 tries).

Oh wow, so to clarify, it boots OK?

Please collect systemd-analyze given lack of any other tool to evaluate
any deltas. Can't think of anything else to gather other than seeing if
it booted.

Issue is that some services (kdump, tuned) seem to take sometimes ages on
that system to start for some reason, 

How about disabling that?

and systemd-analyze refuses to do
something reasonable while the system is still booting up.

I see.

I'll see if I can come up with some data.

Thanks!

If that boots works then try removing the last patch "module: add a
sanity check prior to allowing kernel module auto-loading" to see if
that last patch helped or was just noise. As it stands I'm not convinced
yet if it did help, if it *does* help we probably need to rethink some
finit_module() allocations things.

Okay, will try without the last patch tomorrow.

Thanks!!
