--- Comment #27 from Ville Syrjala <ville.syrjala at linux.intel.com> ---
Hmm. The register dumps look perfectly fine. So the BIOS provided memory
latency values being too low to keep the system happy remains my only theory.

Any chance there might be a BIOS update available for the machine? That might
be worth a shot, although I can't guarantee that any update would affect the
latency values.

In any case, I'll need to cook up some patches to allow run-time modification
of the latency values, so that we can try and see if increasing them would
actually help...
