Hello, I've a machine with a Core2Duo CPU. /proc/cpuinfo reports the flag constant_tsc, but at boot time, I have the log :
... Total of 2 processors activated (6919.15 BogoMIPS). ENABLING IO-APIC IRQs ..TIMER: vector=0x31 apic1=0 pin1=2 apic2=-1 pin2=-1 checking TSC synchronization [CPU#0 -> CPU#1]: Measured 3978592228 cycles TSC warp between CPUs, turning off TSC clock. Marking TSC unstable due to: check_tsc_sync_source failed. Brought up 2 CPUs ... This machine is running 2.6.23.1-21.fc7. I know I should report to Fedora, but I was wondering if this is a bug or a feature ;) Regards, Paul - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
