Hi,

Is the USB keyboard attached prior to panic?

If yes, it should work, unless it is a crash inside the USB code.

If not, this is currently not supported.

--HPS

Just another datapoint. If I get a panic really early on (e.g. a fatal 
trap 12 during the very first part of the kernel's booting process) I 
experience this same issue. I've dropped to a debugger, but can't trace 
what happened because the keyboard does not work.

Using a PS/2 does not work as this machine has no PS/2 keyboard 
interface. :)
