sun x4500 and smp

Thank you Remy! Your recommendation solved the problem. Its been running for over a day now without a single hiccup. 

thanks also to everyone else who took time to respond with help and suggestions. 



At the risk of being a bother, were you able to get all four ethernet devices working? on mine, only the first two are working. the other two get errors on ioport allocation.

Hi Ron, 

Fighted the same problem on mine. It seems to be a problem of interrupts 
dynamic routing on those old good opterons. 

I fixed it by sticking all interrupts to processor 0 (cpuset -l 0 -x 
..). Since then, it works without any trouble.
