<div dir="ltr"><div> I have tried to get a 3.2 and higher Kernel with support for more than 64 CPUs working on an SGI Altix 4700 with no luck. Every Kernel I have built keeps reporting the same error: Non-existent Memory Address Error. I am not sure if this is a Kernel issue or not but I will supply the output from the POD that was entered due to MCA. Any pointers or help would be greatly appreciated.<br>
