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
