I have [ 3618.305918] hpet1: lost 1 rtc interrupts with tvtime running since I switched cpus - so something is wrong anyway. I just wanted to report that for _me_ the behaviour is worse with NO_NEW_FAIR_SLEEPERS and plain 2.6.31. I tried it yesterday when the firefox update came in and I switched between NO_NEW_FAIR... and NEW_FAIR... several times and with NO_NEW_FAIR... tvtime was just _more_ jerky, I am not saying that it wasn't jerky without it nor do I complain about it at all. ;) Gl?ck Auf, Volker -- 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/
