Hi Folks,
	I'm running 1.5V on a i386 machine for a few days now
and today after reboot, I'm being bombarded just after boot with

and now...

(Nothing is physcially attached to the bus right now or at
boot time, except a cable.  Relevant boot stuff:

ohci0 at pci0 dev 15 function 0: Opti RM861HA (rev. 0x10)
ohci0: interrupting at irq 5
ohci0: OHCI version 1.0, legacy support
usb0 at ohci0: USB revision 1.0
uhub0 at usb0
uhub0: Opti OHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered

irq5 is not being shared)


I saw a reference to this on an Alpha back in Feb 2001...
but it looks like it was being ascribed to an machine
interrupt issue?

Is there anything worth persuing on an i386 here?

(Geez moving to -snaphots hurts more than I thought it would. :-(

	Thanks.
