freebsd stable - Nov 2010 - STABLE panics/hardlocks when savage module is inserted

I hate to be the guy who gripes on the mailing list about his dinosaur video
card's drivers crashing his system, but it's possible this could be an
issue
of a wider scope.  When I kldload savage the system hardlocks.  Not exactly
sure if it's panicking or not, however I do have a serial port, so maybe I
can setup a serial console and compile the kernel with debugger support to
try and get a backtrace.

Anybody have any pointers?

This should give you enough of an overview of how to obtain and report
the information you obtain for debugging kernel problems.

http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html

The generic kernel configuration for the most part should be enough
information to start for most cases and this would at least give you a
starting point.

Using a GENERIC kernel from a release or a snapshot too would also help
to determine if its a problem as part of the project or a configuration
mistake you might have made in your custom kernel.
