Well, without the patches I get a panic like so ->
...
APIC_IO: routing 8254 via pin 2
Trap 12
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0x0
stack pointer = 0x10:0xc0329f8c
frame pointer = 0x10:0xc0329f98
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupts enabled, resume, IOPL = 0
current process = 0 (swapper)
interrupt mask = <- SMP: XXX
trap number = 12
panic: page fault
mp_lock = 0000001d; cpuid = 0; lapic.id = 0
WITH the patch I get ->
avail mem = ...
Programming 24 pins in IOAPIC #0
AP#1 (PHY #1) failed!
panic y/n? [y] (choose n)
...
...
panic's same as before.
