Well either the new 2.6.13.2 kernel has some SMP bugs on your type of
system or your second cpu has problems.
If you swap the cpus and boot with it set to 1 cpu, and it fails to
build, then yes I would say cpu2 is bad. If it still passes with that
cpu running, I think the new kernel is buggy or there are other smp
related problems with your board.
