Output is good so long as I put the trailing ",115200" on the command line. But I made early_serial8250_setup() printk() the return value it got from probe_baud() - in case is was somehow getting 115201 or some other silly value ... nope. Exactly 115200. I also can't explain why the "noise" comes and goes a dozen times during boot, Does some other place in the kernel look at the "uart..." command line argument? -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
