Hi all,
I am trying to boot a linux box using kernel v 2.4.13
to use the serial !0 device as its console.
My grub config file contains the correct arguments and the S0 device works
fine for the grub boot loader and for serial login
in run level 3, but the kernel insists on using the keyboard and
monitor as its console during boot and initialization.
I'm including the relevant output from my dmesg
and scratching my head. Can anyone tell me why the
kernel is not using the ttyS0 serial port as its console?
Thanks,
Rudy Vener
dmesg output follows:
