I also ran into an issue w/ this machine where it would panic at
shutdown.  After the panic, all the cpu's would join in the panic fun
and drop to the db prompt also, causing all sorts of fun.  After a
little debugging help from attilio, I changed the device_shutdown
handler to bxe_detach instead, and that prevented the panic at reboot.

The panic would happen both compiled into the kernel and as a module,
but would only trigger at reboot, but not when unloading the module.
I did not test the fix when the driver is compiled into the kernel.
The test fix was also on a kernel w/o WITNESS, w/o SMP and w/o
PREEMPTION, to make things easier to see.

I have put images of the panic, w/ the backtrace up at:

Thanks for your help.
