I have a pretty good idea of what is wrong, and it's partially my fault.
A quick work-around would be to edit /sys/dev/twa/tw_osl_freebsd.c and
remove the INTR_MPSAFE flag as so:
--- tw_osl_freebsd.c 9 May 2007 04:16:32 -0000 1.7
+++ tw_osl_freebsd.c 9 May 2007 04:54:24 -0000

return(ENXIO);
}
if ((error = bus_setup_intr(sc->bus_dev, sc->irq_res,
- INTR_TYPE_CAM | INTR_MPSAFE,
+ INTR_TYPE_CAM,
#ifdef TW_OSLI_DEFERRED_INTR_USED
twa_pci_intr_fast, NULL,
#else
If that works for you then I'll check it into CVS and work with
AMCC on a real fix.
