I've been googling about this off and on for a couple of weeks now and I'm still in the dark.
When I boot my s3c2410 board with a serial console (console=ttySAC0) everything seems to work fine. What I am trying to get is the console showing on LCD (FB0) and input through a USB keyboard.
If I omit the console= or use one of console=tty, console=tty0 along with init=/linuxrc (busybox) I get the LCD display and text typed on the USB keyboard shows up on screen but doesn't seem to be seen by the console.
e.g. I type root for login and hit enter, the screen scrolls one line (newline) but the password prompt never appears.
If I use /bin/ash for init=, then input from the keyboard seems to work fine and I can issue commands (ls, cd, etc).
I figure there's something about busybox's inittab that isn't right for my s3c2410 board and its expecting input from somewhere else. Or, I'm just using the wrong device for console=
Here's the busybox inittab
