ok, i edit'd as you indicated:
--snip--
/* get the PHYSICAL APIC ID# */
physical_cpu = CPU_TO_ID(logical_cpu);
printf("CPU_TO_ID of logical_cpu: %d gives physical_cpu %d\n",
logical_cpu,physical_cpu);
/* XXX: override hack divemojo */
physical_cpu = 11;
printf("OVERRIDE physical_cpu to: %d\n",physical_cpu);
/* calculate the vector */
vector = (boot_addr >> 12) & 0xff;
--snip--
and i set physical_cpu to 1,2,3...,11 as you indicated
rebooting after make'ing and install'ing each kernel gave:
--snip--
avail memory = 517992448 (505852K bytes)

IOAPIC #0 intpin 2 -> irq 0

CPU_TO_ID of logical_cpu: 1 gives physical_cpu 6
OVERRIDE physical_cpu to: 3
WOOT WOOT WOOT

Preloaded elf kernel "kernel" at 0xc03b2000.
--snip--
where the ONLY difference, is the printf of the OVERRIDE physical_cpu,
which was obviously different on each instance since i was changing it in
the code (and just wanted to verify it in dmesg)
basically, EACH kernel edit gave the "panic" msg as indicated in the
snippet
so... any other ideas to try at this point?
thanks
