Presently there is no grep timer or TIMER or 8259A in logs. 8259A has to do with IO-APIC timer? It would make sense that nvnet would see apic and lapic on in bios and linux and look for io-apic timer as well as apic table, then fail confused. Is there a link to that patch? I keep deleting this list it's huge so I lost a patch in a message. -Bob
