what is the specific problem with auixp?  what other devices have trouble
and what's the specific problem with those?

does this patch make any difference?

I made several changes to the ACPI code in the 6.x branch, in these files:


if you revert all of those files to the netbsd-6-0-RELEASE tag,
does that make the problem go away?  if so, could you turn on
MPVERBOSE and INTRDEBUG and send the output from that with ACPI enabled?
(with the current netbsd-6 versions of those files, not the older versions)

also, could you provide the output of "acpidump -dt"?
