>How-To-Repeat:
This is 100% repeateable with mentiones BackUPS
connected to USB port using original APC cable.
1. Boot system into single mode (for simplicity,
it panices in the multiuser too).
2. Run usbd(8) without arguments (won't trigger without it).
3. run "cat /dev/uhid0"
4. Physically detach UPS from USB: unplug its control cable.
Wait until usbd detaches device. cat will fail with i/o error.
5. Plug control cable back, wait until usbd reattaches device.
6. run "cat /dev/uhid0" again and get kernel panic immediately.
>Fix:
Unknown for me.
