I have two dual processor PC. Both of them I didn't intentionally buy
processors of the same batch but they all works fine. I think Intel won't
be that poor in QA for their processors.
The problem in this case is not they didn't work but a wrong recognition of
processor type. Both bogomips and clock are reported correctly. So I
suspect the problem is in the BIOS or Main Board setting. Especially if it
is always the second processor recognized wrongly no matter which
processors you put it.
I cannot sure Linux detect processor type directly or go through BIOS, or
be affected by the BIOS. But I don't expect that is a Linux kernel
problem, or at least, by its own.
I heard about Celeron SMP support was removed. But if this case is using
such Celeron processor, I cannot sure it will work or just reporting a
wrong processor ID.
