Ok, yours is a more odd case. :) This is debatably a bug in your ASL, but =
I=20
think we can work around it. It is routing your USB interrupts to IRQ 10 b=
ut=20
is not using a link device to do it, and it is not including an INTR_OVERRI=
DE=20
entry in the MADT to change IRQ 10 from the default of edge/trigger to=20
level/low. The patch below forces all hard-wired PCI interrupts routed via=
=20
ACPI to be level/low. This patch should apply both to HEAD and 6.x and may=
be=20
5.x.

If you could get a verbose dmesg for this case using a serial console I'd b=
e=20
interested in looking at that too.
