NetBSD 1.6_RC1 (GENERIC_ISDN) #0: Mon Aug 12 22:10:10 CEST 2002
I have an i386 machine with no video card installed and no keyboard attached.  Instead, I have connected a VT220 clone to com0 that I'm using as a serial console (standard 9600 baud, everything default).  As soon as I turn off the terminal the kernel crashes and a friendly "db>" waits for me when I turn on the terminal again.  "trace" shows something with "comintr" - sorry to be to unprecise here but I've never used the kernel debugger before.  If someone could assist me I can also provide a core dump if needed.

Turn off the serial console.
