I am porting linux-2.4.7 to MCP750 board. It booted fine and got bash prompt. It cannot take anything I type form serial console. So, I put agetty to inittab and it passed the command to bash. Anyone has ideas what's wrong? BTW, the same thing happened to me when porting to i386 system using serial console.
Thanks in advance. Ying Lin The follwoing is boot log.
