I've tried the patch on NetBSD-6 and it indeed fixed the issue here. Just like
your previous patch it also introduced a worrying behavior: when i press the
power button the machine powers down *immediately* and is not calling the
shutdown hooks, neither in userland nor in the kernel. This used to work fine
but i am not sure it is related to this PR.

Since i dont know ACPI that intimately, y working hypothesis is if i press the
power button, the ACPI subsystem is passing that interrupt to NetBSD and it is
not processed correctly it is shutting down the machine hard immediately. So
are the ACPI interrupts reaching NetBSD?
