ACPI on thinkpad t495

[Vitaly Shevtsov <shev.vt1984%gmail.com@localhost>]

Hello!

I have a thinkpad t495 (AMD Ryzen powered)

Neither NetBSD-current nor 9.3 cannot boot on it. It hangs on:
[<time>] ugen1: vendor 06cb (0x06cb) product 00bd (0x00bd), rev
2.00/0.00, addr 5

If I boot with no ACPI support (boot -2 from the loader) then it boots fine.


Is there a way to boot it without disabling ACPI? Maybe recompile the
kernel with some specific options?

Thanks,
Vitaly
