Thanks, Hans. Here's some output from <vmstat -i>:
interrupt total rate
irq1 atkbd0 48 0
irq16 uhci0 19937714 43248
irq18 atapci0+ 886 1
[snip]
There are no other UHCI's in the list.
A <dmesg | grep uhci> produces only one instance at uhci0:
"uhci0: <UHCI (generic) USB controller> port 0xff20-0xff3f \
irq16 at device 26.0 on pci0"
Is there another command you're thinking of to produce better information?
