In reguards to seeing messages on minicom, what logger do you have installed? Can you just shovel kernel messages over to ttyS01? eg sudo tailf /var/log/kernel ttyS01
andystewart> I did that per your suggestion and it works just fine. Umm, it works just fine so long as the system is up and running. You really want the kernel to be printing directly to the console. Otherwise, when the system locks up and the NMI fires, you still won't get your messages over the serial console. Andy, it looked to me like you had things configured properly. Indeed, I use a very similar setup all of the time. The only difference is it works for me. (I hate that phrase). I'm not sure what to suggest at this point. If you do an alt-sysrq-h, does that at least print out over the serial console? -Jeff
