Thank you for the long awaited x86_64 port! Looking through the RedHat pages concerning their EL releases, I find that the ES and WS versions claim to support only 2 CPUs while the AS version supports, well, more. With the CentOS releases following the ES releases, can I assume that this too is limited to two CPUs? Is this a kernel issue or something else? Should I be thinking of loading a non-CentOS release on a quad Opteron box? Thanks, Bill
