ebx is 0

It has been at least 10 years since I last used any debugger,
and even then it was minimal, so the more detailed your instructions
the better. :) The above is from 'show registers' at the ddb 'db>'
prompt right after the panic, and not from gdb; nor did I do anything
to make it be at "m->m_len = len;"

I am no longer able to make the system panic 100% of the attempts any 
more. It did panic after three attempts, and is now sitting in ddb, so
at least at the moment I can provide more data as needed. This is
currently a testbed, so there is no immediate need to reboot it.
I could keep it in ddb for several days, if needed, though I suspect
it should not be too hard to get it panic again. But for the next
few hours/days, I can provide more timely data as needed.
