I posted this message a couple days ago and realized that the replyto
address was incorrect.  Sorry for the inconvenience to the group.  I've
fixed it since, so if anyone has any ideas on this problem, I could
really use the advice.

(The crash is:
kernel: page fault trap, code = 0
stopped at _tcp_input:0x27a
if that matters)

The changes I've added to the TCP code in NetBSD cause it to crash (of
course).  This I don't mind.  However, I've compiled in DDB which
catches the panic (which is useful).  I cannot get DDB to dump core
though so that I can later use kgdb to analyze the crashdump.

I've looked at the FreeBSD site which suggests typing either:

db> call diediedie()
or
db> call panic()

both of these give this response:

Faulted in DDB, continuing

So I've got to call cpu-reset() which gives me no crashdump.

I'm running NetBSD 1.1 on a pentium 100MHz, 32MB RAM.

On a related note, I think I made the swap partition too small (just
over 32 MB) - which seems to be keeping the crash dump from working
correctly even when DDB is not configured.  Is it possible to use a
crash file like L*n*x does?

Any advice much appreciated.  Thanks in advance.
