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?
