So this panic also exists in RELENG_5_4, and I have managed 
to get a dump of it.

First a few words about the system:
uname -a:
FreeBSD kvip88.kvi.nl 5.4-RELEASE FreeBSD 5.4-RELEASE #1: Fri May  6
16:03:32 CEST 2005

I did a fresh cvsup/buildworld/buildkernel today. Kernel config
is attached below. Panic is 100% reproducible by just pressing any
key during boot, and even sometimes on the live system (it happened
only once for me, when I pressed a key on vty0, which has no getty
running). This specific dump was taken at the very early stage of
the boot sequence, just after attaching swap space. Unfortunately
unlike in the examples from developers handbook I can't get a 
panic message back from a dump (is it because I compiled a debugger
into the kernel and called panic from there manually?), but stack
trace starting from entry 24 corresponds to the one I saw there.

PS.
Why doadump() refuses to write a 511Mb big dump into 512Mb
swap partition?

PPS.
Do I really need a "option KDB/DDB" in the kernel to get dumps?

Best regards,
  Alexander.
