This was reported downstream in Fedora as well: https://bugzilla.redhat.com/show_bug.cgi?id=2323584 .

Hi,

is this warning reproducible on your system only during the initial startup/booting the kernel? If you then manually load/unload 'ucsi_acpi' module, are there any errors observed in the log?

Do you have something like the following in the kernel log (dmesg)? Does it happen when the WARNING occurs or when it does not occur?

[    6.482546] ucsi_acpi USBC000:00: failed to reset PPM!
[    6.482551] ucsi_acpi USBC000:00: error -ETIMEDOUT: PPM init failed

I've also encountered these "failed to init PPM" errors and the WARNING. Looks like PPM is not quickly responsive at the kernel startup phase. That's strange but as a straightforward solution the attached patch helped me. It turns out that it takes around 8000ms for the PPM on my laptop to start responding during kernel startup when the selected timeout in the code is 5000ms. You can check the patch. If it still won't help, try increasing the timeout some more. Otherwise, the cause seems to be hidden in another place..

Also checked various kernels, and "failed to init PPM" errors go back to 5.12 kernel at least on my system so that's probably not a recent regression. I'm not talking about the WARNING - it appeared much-much later and probably just revealed the problem clearer.

[PATCH] usb: typec: ucsi: increase timeout for PPM reset operations

And this contains a patch proposed by Christian A. Ehrhardt. You can try this, too, of course. But in my case it unfortunately didn't help.

only during boot

Yes, something similar but in the call trace

Sorry for the stupid question, how do I recompile only the module and not the entire kernel after patching?

Well, googling "compile a single kernel module" gives a lot of useful links. I think the top ones will contain the needed info..

E.g. https://yoursunny.com/t/2018/one-kernel-module/

Any success with that ..?

The procedure is a bit outdated but I found an updated one specifically for Arch on their wiki. I'm testing it. So far it seems OK. Thank you!

I see it in 6.14rc3:
