It happens on all AMD CPUs when configured as generic 686 because the CLOCK_TICK_RATE for the AMD boxes seems to be 1189200 instead of 1193100 - so after "correcting" the tick rate in linux/include/asm-i386/timex.h (at the top of the file) - the problem is resolved and your test code schows the expeced 0 +/- 32 (on an idle system - under load the +/- will off course increase). pleas cross check on your system if this solves it for you - if it does not I would need detailed specs from the system (checked here on three different AMD archs (ELAN SC520, AMD Duron , AMD XP)). hofrat _______________________________________________ Rtl mailing list [email protected] http://www2.fsmlabs.com/mailman/listinfo/rtl
