I'm not sure. I know that I'm getting two processors to boot now. Top
reports both processors, and I get two little penguins on FB boot
-always an important indicator.
I found this bug reported and commented on by you and others several
times over. It looks like a known issue at this point. If there's
anything I can do to help debug/test, let me know.
It might be worth inclusion in the Unofficial FAQ that a couple of
possible workarounds are to disable APIC in the BIOS or add "apic=force"
to the kernel boot params (from another bugzilla comment).
