Greetings, 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 saying "xhci_set_hw_power:". Any help on how to track the issue behind this down would be greatly appreciated. Since reboot I have had a usb disk plugged in and removed again. I also unplugged the keyboard for a while. Regards, Andréas
