OK.  I've tried polling mode and it does not appear to make any
difference.

This was my first thought too.  But I've carefully examined all the
information I can gather about irqs in use in my system and it looks to
me like 9 and 10 are not in use.

The system has two pci busses and an isa bus.  Here's a map of the bus
layout with allocated irq's (constructed from the dmesg):

root
	pcib0: <ServerWorks NB6536 2.0HE host to PCI bridge> on motherboard
		IOAPIC #0 intpin 19 -> irq 2
		IOAPIC #0 intpin 18 -> irq 11
		IOAPIC #0 intpin 17 -> irq 15
		pci0: <PCI bus> on pcib0
			Matrox MGA Millennium II (irq 2)
			Matrox MGA Millennium II (irq 11)
			Intel 82557/8/9 EtherExpress (irq 15)
			Promise TX2 ATA100 controller (irq 16)
			Generic PCI ATA controller (irq 15)
				ata0 (irq 14)
				ata1 (irq 15)
			isab0: <PCI to ISA bridge ...>
				isa0: <ISA bus> on isab0
					fdc0 (irq 6)
					atkbd0 (irq 1)
					pcic0 (irq 9)
					sio0 (irq 4)
					sio1 (irq 3)
					ppp0 (irq 7)
					sbc0 (irq 5)
	pcib1: <ServerWorks NB6536 2.0HE host to PCI bridge> on motherboard
		IOAPIC #0 intpin 23 -> irq 17
		IOAPIC #0 intpin 20 -> irq 18
		IOAPIC #0 intpin 21 -> irq 19
		pci1: <PCI bus> on pcib1
			OHCI (generic) USB controller (irq 17)
			Compaq Netelligent 10/100 TX UTP (irq 18)
			sym0: <875> (scsi) (irq 19)

Based on this I have these irqs in use:

1  (atkbd0)
2  (vga)
3  (sio1)
4  (sio0)
5  (sbc0)
6  (fdc0)
7  (ppc0)
8  (rtc)
9  (pcic0)  (unused if I don't declare pcic0 there in kernel config)
10 (... unused ...)
11 (vga)
12 (mouse - not currently attached)
13 (npx0)
14 (ata0)
15 (ata1, fxp0)
16 (atapci0)
17 (ohci0)
18 (tl0)
19 (sym0)

Is there some reason why I can't use irq 9 or irq 10?  There is no mention
of 9 or 10 in the dmesg or "vmstat -i" output.

Full dmesg is in my previous email and at
