Thank you for the great work u've done! FreeBSD's really rocks :)

so,

While turning off the computer - it has successfully done all the shutdown job, displayed the uptime, and shown:

usb1: timeout

after this - the system has hung with 100% CPU load.
>How-To-Repeat:
Run FreeBSD on latest VMWARE, with usb support switched on. Run KDE. Disable VMWARE's USB support for the guest OS. Reboot.
The guest OS will hang and eat the CPU :)
