Pentium D - Dual-Core problem

I have a Pentium D 820 processor on an ASUS P5RD1-VM motherboard.
My kernel is compiled to support SMP and otherwise works without issue.

The problem I have is that the 2nd core does not seem to work.
This part of the dmesg output seems relevant:

Code:

CPU0: Intel(R) Pentium(R) D CPU 2.80GHz stepping 04

Booting processor 1/1 eip 2000

Not responding.

Inquiring remote APIC #1...

... APIC #1 ID: failed

... APIC #1 VERSION: failed

... APIC #1 SPIV: failed

CPU #1 not responding - cannot use it.

Total of 1 processors activated (5679.96 BogoMIPS).

ENABLING IO-APIC IRQs

..TIMER: vector=0x31 pin1=2 pin2=-1

Brought up 1 CPUs

Is this a sure sign of bad hardware or might there be some issue I have overlooked?

I have the same problem

I posted about it on the Fedora Forums

However, have not found a solution for it. If I do, I'll post here and there. Hope you'll do the same.

A link to my Fedora Forums post might be helpful ...

I have the same problem with a Quad core Q9300, but I see the issue ONLY if I go into the GRUB boot menu and choose Linux (instead of letting it boot by default into Linux).

Yes, this is not much of a problem unless I need to boot into an older version of the kernel.

Adding noapic didn't help.

But adding options "noapic nolapic acpi=off" and removing the "quiet" option succeeds about 1 out of 5 times!

I will update if I find anything new. If others find something new, please post it here.

Thanks,
