Agreed. I thought about buffering in the slow console driver itself but that's bad because if it's a crash message we might not get the events (interrupts, or whatever) in order to make forward progress printing out the buffer, and thus we'd lose the valuable messages. - 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/
