I tried building a kernel with LOCKDEBUG, but that hung about halfway
through the /etc/rc.d/ scripts, so I gave up on it. I've just managed
to get a proper core dump from a hang. Didn't write down the backtraces
for the various CPUs, but one was doing disk I/O, one was in pf handling
a fragment (and calling kernel_lock()), one was in ipmi (again, calling
kernel_lock(), I think), and the final one was servicing some interrupt.
If there's anything I ought to pull from the dump, please let me know!
If LOCKDEBUG hangs, you have problems.... I'd try to get more information
on that first.
