[Soekris] Serial console

[Andi Reinbrech]

Hi,

Has anyone got a working 2.6.20 kernel on a serial console?  I have a
2.6.12 that came with the preloaded software on my soekris board, and it
works 100%.

I need to upgrade the kernel to 2.6.20 because this version includes
native support for my USB Serial Bridge, but I can't get it to boot
properly using ttyS0 as the main console.

I get an error "Warning: unable to open initial console", but all the
normal kernel printk's before that warning are printed onto the serial
console, so the 8250/16550 kernel support is working 100%.  Because this
seems to work I can only assume that my problem is .config or udev
related?

My kernel is set to boot with "console=ttyS0", and like I mentioned, the
console messages are in fact printed to the serial port.  After this
warning message, the system seems to be running, as I get messages to the
serial port when I add/remove my USB flash drive.  The problem seems to be
that the getty doesn't want to start on the serial port.

Does anyone have any ideas, or a working .config I can try?

Thanks,
Andi
