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.
Here is my uname:

After taking a look at dmesg I'm not sure if I just now noticed this or if
it has recently started doing this:

I'm really not sure how to go about troubleshooting this issue. Can someone
point me in the right direction?
Thanks in advance.
