Not sure if this is mis-calibration or just bad-interaction w/ kthrt. Mind sending a dmesg to me? > and 'pit' seems to produce errors (system will not switch from pit to > another clocksource anymore): Do the TOD patches have this issue by themselves, or is this only with kthrt? I know I had some issues with non-continuous clocksources (pit, jiffies) with the kthrt patch, where it wouldn't fall back to non-high-res when the clocksource stopped supporting it. thanks -john - 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/
