Actually this does make something pop out in my mind.

In your failing log above you had shown this:
> [    4.295526] kernel: Disabling IRQ #9

By this happening before pinctrl_amd is loaded might mean that IRQs are not
being serviced anymore for the ACPI SCI driver.  When pinctrl_amd gets loaded
it tries to service IRQ 9 stuff, but it's not destined for that driver and then
you see an IRQ storm from ACPI interrupts.

So IMO continue to monitor to see if putting it into the initramfs helped the
problem afterall, but please leave the dynamic debugging for pinctrl-amd in
place on your kernel command line in case it comes back and we need to look at
the timing of the error and pinctrl-amd loading.
