Re: 36 Second Boot Gap on Asus Laptop (Slow boot time)

Looks like it's polling for some GPU and incrementally waits (12s total, you limit this ti 3.6s) if there's no response.
Do you get "PEGP" related errors in the dmesg/journal?
Can you toggle an APU/GPU in the BIOS/UEFI?

Re: 36 Second Boot Gap on Asus Laptop (Slow boot time)

Found a workaround.
Add:

gpiolib_acpi.run_edge_events_on_boot=0

to the kernel params, this fixed the 36s hang for me (ROG Strix G16 G614PP_G614PP)

I rebooted with initcall_debug and found the culprit:

[    1.739645] calling  acpi_gpio_handle_deferred_request_irqs+0x0/0x40 @ 1
[   38.077788] initcall acpi_gpio_handle_deferred_request_irqs+0x0/0x40 returned 0 after 36338138 usecs

Might be related to the ASUS ACPI firmware bugs.
