Unfortunately without a traceback the panic string is useless
since it gives you no clue about how the system got into that
state. This kind of panic is often a secondary effect of
some other problem.

I can cause this to happen almost at will with a Netgear GA311.
It only happens at boot. It will reboot after the panic just
fine and, for me, it only happens repeatedly after I do a
restart boot from XP. It has never happened if I shut the
system down first. I have moved many GBs of distfiles and
packages with out causing a panic.

I haven't found a way to cause a dmp when it panics. At least,
what I have read doesn't work. So, how can I get a dmp, which I
can provide a traceback?

What happens when you 'call doadump' from DDB?

I haven't be able to invoke the debugger at the boot panic and even
adding dumpdev to rc.comp doesn't produce a dump file. The /swap
and /var are large enough to dump memory.

I also haven't added DDB to the kernel config. I guess I need to
first get my Digital Rebel, so, I can keep a copy and see what is
on the screen when it panics.

Well, if you don't have DDB in your kernel config, you certainly
won't be able to invoke it when it panics ;-)

hehehe - of course :)

One thing, the developer's handbook only talks about "option DDB" but
that won't compile until you have added KDB.

Now, I got it to panic but it took 5 or 6 tries. "At will" must have
heard his name and ran away :). However, when I try "call doadump" it
says no dump device has been specified. I have dumpdev="AUTO" in
rc.conf but I think this is happening far to early.

All is not lost because I think I have 3-6.3 MP images of the panic and
the trace back. How can I get a dumpdev that early into the boot? This
is turning into the pain I thought it would be :).
