And it's definitely taking the MAX_TIMEOUT case (wait forever) in schedule_timeout().

Does that mean this is a minicom problem because it didn't specify a timeout? - 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/
