I changed schedule_timeout() to call the new del_timer_sync instead of currently del_singleshot_timer_sync in attempt to stress these set of patches a bit more and I just observed a kernel hang. The symptom starts with lost network connectivity. It looks like the entire ethernet connections were gone, followed by blank screen on the console. I'm not sure whether it is a hard or soft hang, but system is inaccessible (blank screen and no network connection). I'm forced to do a reboot when that happens. - 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/
