Hi,

I've recently tried to start the kernel on my newly constructed
1.44M SSTO floppy (from today's sources).  The autoconfig phase
finds all my hardware, but a short while (4-5 seconds) after
printing "biomask c040 netmask c040 ttymask c04a" at the end of
the autoconfig phase, the machine resets with no warning.

This is what I've done to debug this so far:

 o I have put in DIAGNOSTIC, DEBUG and DDB in the kernel, the
   machine still resets.

 o I have trimmed away unused hardware from my INSTALL kernel,
   the machine still resets.

 o I have put calls to Debugger() around the call to spl0()
   inside configure() in autoconf.c, and it stops at the first
   one but never reaches the second one (it resets, as before).

The machine I'm doing this on is a Dell Latitude XPi CD, with a
150MHz Pentium.  It has a modem card and a 3com ethernet card
installed in the two PCMCIA slots.

Right before it prints the "biomask ..." stuff it appears as if
there is coming some brief "random noise" from the built-in speaker
(the machine has audio hardware which isn't supported (yet?) and
isn't configured into the INSTALL kernel, it's an ESS1888).

I also tried to pull out the modem card, but the machine still
resets.

I just noticed something I found slightly strange, it appears that
NetBSD hasn't given a "card IRQ" to my ethernet card, at least it
didn't say "card irq" for pcmcia1 in the autoconf messages.
Attached below is the autoconfig messages from my laptop (copied by
hand).

Anyone have any idea where I should look next to debug this
problem further?
