hmm. It sounds like your result is real then.

I assume you mean the same configuration as for the dual
cores?
With the 2.6.x kernels being released as snapshots rather
than working kernels, to get functionality sometimes I have
to run through a whole series of kernels to find ones that
are functional. I tested about 50 from the last 2yrs
recently and found that only half had a particular
functionality I wanted. Even within a series you'd get a
string of kernels that work and then a set that don't work
and then at the end they do work again. The other day I
copied my working 2.6.x laptop setup to a desktop machine to
find that the drivers for 3 different ethernet cards (3Com,
Intel e100, Netgear tulip) wouldn't load even though all
devices were seen on the pci bus.
Whether this is relevant to your problem I don't know, but
I'm pretty frustrated with the 2.6 kernels.
I don't know what effect the quad core is having. Can you
turn off 2 of them in the BIOS just for a test? Can you try
a 2.4 kernel, or any other 2.6 kernel?
