Did you read Intel documet 320839-009, August/2009, already?  It is at:
http://www.intel.com/Assets/PDF/specupdate/320839.pdf

I see some stuff there that might be a problem, many of the "issues" are
related to interrupt handling.  Errata 40 (EOI to IOAPIC can be blocked)
even states that one should avoid the X58 IOH IOAPIC on stepping B2
completely, and use the IOAPIC in the ICH10R instead.

And the B2 stepping is the one in most motherboards (B3 is quite new).
