this is odd. (but encouraging).. the one thing I can imagine oprofile doing is disabling the nmi_watchdog... you can simulate the same effect by passing "nmi_watchdog=0" on the kernel commandline (and there's something in /proc/sys as well to disable it at runtime) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
