Hallo Liste,
hat vielleicht jemand Ahnung, ob man fuer die Opterons mit Dual Core
den 2.6.12er Kernel noch patchen muss damit er den Doppel-Kern erkennt?
Ich habe hier nen IBM @server e326 mit Debian pure_amd64 installiert,
dieser besitzt zwei Dual Core CPU's, habe mir dazu einen 2.6.12.4er
Kernel gebaut.

Jetzt habe ich erwartet das ich 2 Nodes und 4 CPU's angezeigt bekomme.
Oder sehe ich die Sache falsch?
