Hello Thomas

The Rm9000x2 revision 1.1 and 1.0 does not have support for the five state MOESI protocol and can only support SMP if appropriate hacks are applied to the memory management code. The revision 1.2 of the chip does support MOESI protocol and SMP. I am sure PMC can provide you with the necessary sources. Which board are you using?

Thanks
