Dagnabbit.. it's done it again.. went from 100-200 wakeups/sec back up to 20000+ wakeups/sec. This time *with* the powertop patches in place. Somethings broken in there, but I don't know what. Or how to make it happen on demand.. it's fine after rebooting again. ??? At least now I know to look when I hear the fan turning on when the system is otherwise supposed to be idle.. 2.6.23 did not have this problem. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
