Problems with xhci driver

I seem to have encountered a problem with the xhci driver on my new
computer (FreeBSD 9.0). I noticed that I had a 15% interrupt cpu usage
when the machine wasn't doing anything so I looked into it and it turns
out that the xhci driver is going nuts on me.
A vmstat -i shows me this:
interrupt total rate
irq16: xhci0 16747312710 101948
I tried setting hw.usb.xhci.debug to 1 and then I got repeated logs
Any help on how to track the issue behind this down would be greatly
Since reboot I have had a usb disk plugged in and removed again. I also
unplugged the keyboard for a while.
