>Release: FreeBSD 2.2.6-STABLE i386
>Environment:
Any FreeBSD 2.2-STABLE we have with PS/2 keyboard (ATX or proprietary
motherboards). Kernels vary but about display/keyboard related things we
do use pcvt, if that matters.
>Description:
When unplugging and replugging the keyboard, the system immediately
panics. This is highly repeatable here. This happened only with PS/2 type
keyboards before, but now we are seeing it in other types of hardware as
well, so it might be that the rot is spreading.

>How-To-Repeat:
remove and replug PS/2 keyboard, or use an mechanical
monitor/keyboard switch. If it does not happen, add PCVT to kernel and
retry. If still no success, as me to send you a couple of kernels. I can
also provide crash dumps if necessary.
