ACPI, USB troubles.

[coypu%SDF.ORG@localhost]

Hi, I've got a problem with ACPI as follows:

XHCI hand-off on:
1. boot with ACPI on - USB keyboard does not work at all.
2. Reboot (not shutdown!) and choose ACPI off - keyboard interrupt does
not work, USB mouse interrupt works for keyboard.
3. Reboot again and choose ACPI off - devices act normal

XHCI hand-off off:
1. Boot with ACPI on - USB keyboard interrupts not used, USB mouse
interrupts work for keyboard.
2. Boot with ACPI off - normal.

I've noted that acpidump contains highly OS-specific data, even
specifying 'FreeBSD', 'Windows 2001 SP1'... Of course, NetBSD is not one
of the options, and probably ends up in some 'else' case.

Can I somehow pretend to be FreeBSD and see if it magically fixes the
problems?
Guessing the 'else' case is plain broken.

I've filed this as kern/50586, but I recommend people look at this
mirror:

Because I didn't realize how long the ACPI dump data is at first.
