I've also enabled hyper threading (append="acpismp=force"). Here's the output from /proc/interrupts: brynhild:bash$ cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 3033 2911 2871 2880 IO-APIC-edge timer 1: 1 0 2 0 IO-APIC-edge keyboard 2: 0 0 0 0 XT-PIC cascade 8: 1 0 0 0 IO-APIC-edge rtc 18: 5 3 3 4 IO-APIC-level aic7xxx 19: 480 421 412 529 IO-APIC-level eth0 20: 5 3 4 4 IO-APIC-level aic7xxx 21: 5 3 4 4 IO-APIC-level aic7xxx 27: 588 1010 654 943 IO-APIC-level megaraid NMI: 0 0 0 0 LOC: 11530 11528 11528 11466 ERR: 0 MIS: 0 And, you've gotta like this line: Total of 4 processors activated (14299.95 BogoMIPS). I'm going to do some testing on it to check it's stability. I'll let you know the results.
