At nigth then I send the log.
Unfortunately, a known issue with FreeBSD 8.0 is that the new USB
stack, while a vast improvement over the previous USB stack in
countless ways, does not support polled access from DDB. You will need
to use a serial port, firewire port, ps/2, or AT keyboard in order to
get interactive DDB support.
If that's not feasible, or if it's just easier, you may be able to use
the DDB scripting facility + textdumps to run DDB commands
automatically on panic to produce useful debugging output. Take a look
at the textdump(4) man page for details. This can be combined with a
traditional crashdump to capture both DDB output and normal dump data
for use with kgdb.

This is a NULL pointer dereference in the kernel. Per Attilio's e-
mail, a
stack trace should help us track it down. Thanks!
