Revision 1.59 of sys/i386/isa/intr_machdep.c added the return to the
following block of code (in icu_setup()).
#if defined(APIC_IO)
if ((u_int)intr >= ICU_LEN) /* no 8259 SLAVE to ignore */
#else
if ((u_int)intr >= ICU_LEN || intr == ICU_SLAVEID)
#endif /* APIC_IO */
+ return (EINVAL);
if (intr_handler[intr] != isa_strayintr)
return (EBUSY);
I'm not sure if the above change is correct but I'd be interested to see
if the problem goes away if you prevent IRQ 9 from being assigned.
