Hi Mika,

Thanks for looking into this. Happy to dig deeper.

Here are the requested dumps (boot with initcall_debug, no workaround):

dmesg: https://gist.github.com/kylan11/63ec3ec319cd6bcaa043fa0b1366965a

acpidump: https://gist.githubusercontent.com/kylan11/7956bbf75714265107f0886f6ed2a381/raw/1614845eb1dc6ab7e2effb6fe56b585a746abe4f/gistfile1.txt

Some quick notes:
- The AMD GPIO controller probes successfully (LINE 2077)

- The hang occurs in the deferred IRQ handler (line 2960)

- There are some ACPI errors around 0.285373 to 0.289806, though they complete quickly

- After the 36-second hang, everything else initializes normally. 
touchpad, audio, wifi, nvidia GPU all work fine.

The ACPI tables show there's a _AEI method under \_SB_GPIO. Not sure if those
unresolved GPP2/GPP7 references are related to what's blocking the deferred
IRQ handler, or if it's something else entirely.

Let me know if you need anything else or want me to test something specific.

Thanks,
Francesco
