So do I, and as we already know, I use the same combination of
board and cpu(s).

confirmed..

I'd rather think that this is a problem
in the APIC code of the kernel and this specific combo.

Had Gigabyte done something wrong in the APIC implemenation?

Are there people who use the Gigabyte 586DX with a new kernel
(and maybe without VDR) and having no problems with 2 CPUs?

Pity, I'd really like to use both of my processors :(
