You might have to do what I did to debug the ehci problem and scatter
printf's throughout the shutdown code.  I wasn't able to break into DDB
from the console when my machine hung, the motherboard in question
doesn't have a serial port, I wasn't able to get kgdb working with
/dev/fwmem, and it doesn't appear to be possible to debug event handlers
using kgdb over firewire.
