If you have a non-USB keyboard you might find that you can get a
backtrace:  the necessary code for using keyboards with interrupts
disabled hasn't yet been written under the new USB stack (I have no idea
when it will be done, but it's listed as being necessary for 8.0 to be
released on http://wiki.freebsd.org/USBTODO).

Anyway, you may well have luck using ddb scripting to save traces, see
the ddb(8) manpage.  Without a trace, this may be hard to debug.

Thanks,
