Signal 11 when compiling kernel

Hi,

We've recently got a 2 CPU Lion, but when compiling, it randomly gets Signal 11. I assume this is the same as IA32 (faulty hardware) -- I've pressed F1 before the EFI boot prompt. Can anyone guide me around the maze of options?

Are there any options in there I could tweak to prevent these signals, like adjusting RAM timings? This is under 2.4.0test7-000823, btw.

Many thanks,
Jon.
