This is Fedora 8 and it already has the highres-timers code in x86_64. But I was still comparing 2.6.22 on i386 to 2.6.23-rc5-git1 + highres-timers on x86_64. 2.6.23-rc5 on i386 seems okay too, so whatever is happening it only occurs on 2.6.22 here. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
