Well I had a few minutes this morning, so I swapped CPU0 and 1 and still have the same results. Boots in single proc mode, APIC errors on a dual-proc kernel. (For what it's worth, both CPUs are recognized by the BIOS and report "MP capable".
I checked the Asus website and I'm at the latest beta kernel...
Tonight I'll bounce back to the 1800+s to see if it's a BIOS thing...
Any other suggestions?
Thanks, AndyB
