vmstat questions

[Morgan Wesström]

Hi. This is my "vmstat -i" from my newly installed 7.2-RELEASE-amd64:

# vmstat -i
interrupt                          total       rate
irq4: sio0                          1105          0
irq17: em1 uhci1+               10921807        182
irq19: uhci3++                   8196905        136
cpu0: timer                    117164643       1956
irq256: em0                      7346687        122
irq257: re0                       166625          2
cpu1: timer                    117164471       1956
Total                          260962243       4358

For a long time I've tried to find out what the + and ++ means. Can
anyone shed some light on that?

Also, where did my atapcis on irq19 go? I'm pretty sure I had them
listed there in 7.0-RELEASE.

dmesg snip:

uhci3: <Intel 82801H (ICH8) USB controller USB-B> port 0xd480-0xd49f irq
