But BIOS correctly reports x1/x2 depending on number of CPUs I plug into motherboard, so I believe that it did some initialization before it start loading OS. calibrating APIC timer ... ..... CPU clock speed is 797.0452 MHz. ..... host bus clock speed is 99.6305 MHz. cpu: 0, clocks: 996305, slice: 332101 CPU0 cpu: 1, clocks: 996305, slice: 332101 CPU1 checking TSC synchronization across CPUs: passed. Setting commenced=1, go go go mtrr: your CPUs had inconsistent variable MTRR settings mtrr: probably your BIOS does not setup all CPUs Best regards, Petr Vandrovec vandrove@vc.cvut.cz - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
