0.0% user, 0.0% nice, 0.0% system, 53.8% interrupt, 46.2% idle - Unusual interrupt use?
Recently I've had an unusually high amount of 'interrupt' cpu usage. I stopped all my jails so the box is for the most part idle.

vmstat -i and systat will be useful at identifying what is causing the interupts. Vye Wilson wrote: Recently I've had an unusually high amount of 'interrupt' cpu usage.

Anything plugged into USB if so try removing it as uhci1 is clearly your issue.

I do not use usb at all on this paticular server. The only ones on it are the 2-4 onboard ones. Removing uhci from my kernel fixed this issue. Thank you.
