Check your ACPI settings in your BIOS and in your kernel. I messed with
ours on a couple of servers, I don't remember where I landed, but I
think the only thing that worked reliably was just compiling the kernel
to do processor enumeration via ACPI only. Or shut off ACPI in your
BIOS altogether and the kernel should do the "right thing" regardless of
the compile time options.
This is a shot in the dark, not sure if it will help you at all.
This also might be related to the "High Memory Kernels and buffer
bouncing" thread on this list from 4 December.
