Excellent!  I figured you had something in store; just wanted to make
sure.  Thanks.

I have our kernel set up to issue a full symbolic stack trace and
register and stack dump upon panic/oops.  This is actually much better
and more reliable than a dump in most cases as it is done directly on
the machine in question so there is no need to match up kernels from
releases and what not.  This information goes into the log
file /var/log/messages (if you're living a clean life) and is therefore
retrievable with a system get all after a reboot.

On BSD, all we were able to do with a crash dump was get a stack trace,
and then only about half the time, I'm told.  So this is more than an
equivalent of previous capabilities.

Cheers,
