I did a plain ./configure the first time.

Now I've rebuilt gnumach with --enable-kdb and got slightly different
results. Instead of a reboot, the sytem halts with a visible error
message:

Starting MTA: Panic: zalloc: zone ipc ports exhausted
Kernel Breakpoint trap, eip 0x1179d7
Stopped at 0x1179d6: int $3

Next I rebooted on the working Debian gnumach and set the MTA not to
start. This time I got a similar crash message when inetd tried to
start.

Hurd seems to be crashing at the point when anything that uses the
network starts up. Possibly because TCP/IP isn't working in my gnumach?
I've downloaded the Debian gnumach source package and noticed they have
at least one patch in there that might affect networking. Any
suggestions?  I guess I could start applying the Debian patches
one-by-one until I find the one that fixes it?

I hadn't tried that before but in single user mode, everything seems to
boot up with no problems. It only crashes in multiuser mode. That makes
sense with the new information above, since it's only crashing when the
network is accessed.

Hmmm... if I disable the Hurd console, will I still be able to get to
some sort of a prompt where I can re-enable it later?
