xHCI Interrupt Issue?

["Gary Duzan" <gary%duzan.org@localhost>]

   Booting a freshly built -current amd64 install image seems to mostly work on
my netbsd-7 box, but the kernel gets stuck on:

uhub0 at usb0: vendor 1033 xHCI Root Hub, class 9/0, rev 1.00/1.00, addr 0

However, if I press keys on my PS/2 keyboard, the boot process continues and
I get the installer. (Full dmesg included below.)

   Is this a known issue? Is there anything I can do to help diagnose it?
I'm up for whatever code hackery may be required. 

   Thanks.

					Gary Duzan
