As mentioned in an earlier report, the above patch fixes the panic but results
in a hard hang with mp kernels.
With current sources, the hang problem remains with the amd64 mp kernel
(haven't tried any other permutations). Since neither the serial break or
ctl-alt-esc sequence were recognized by ddb, I searched for an NMI hardware
solution and found the "PCI Dump Switch" card from connecttech.com but with no
apparent online resellers. I then learned how to use virtualbox's NMI
simulation.
Using NMI to break into ddb, it appears the hang is in __mp_lock() (more
precisely arch/amd64/amd64/lock_machdep.c:50). I'm over my head at this point
but thought describing how to duplicate the problem in virtualbox might be
useful to those more skilled. I tried to get a crash dump but that's probably
impossible with the spin lock hang.
I've appended two ddb sessions as well as the dmesg + startup prelude to the
hang.
