When i boot, it says "Broken MP Table Detected"
Then it uses a work around.

(dmesg output, 3.4-Stable)

Intel Pentium detected, installing workaround for F00F bug
APIC_IO: Testing 8254 interrupt delivery
APIC_IO: Broken MP table detected: 8254 is not connected to IO APIC int =
pin
2
APIC_IO: routing 8254 via 8259 on pin 0
changing root device to wd0s1a
SMP: AP CPU #1 Launched!

Perhaps that work around is broken on 4.0, which is what is causing me =
the
problems. I have NEVER had a problem with SMP on 3.x.

I built a very simple 4.0 kernel with just the bare essentials. (ie, ad
driver, and SMP) and it still panics and spontaneously reboots.
