I'm not really the Linux guy here, but I think these are the kernel configuration options:
Device Drivers --->
Character devices --->
Serial Drivers --->
<*> Altera JTAG UART support
Support for console on Altera JTAG UART
If you have Nios serial support selected (on the same settings page) make sure that "Support for console on Nios UART" is not selected. You should have only one device selected as the kernel console, this is where the kernel prints out its messages (boot messages, etc). Dennis Scott Microtronix Datacom Ltd.
