I have tried using another serial cable (as suggested by Wolfgang) but it
made no difference, but I did not expect it to as I get all the messages
from the bootroms OK.
I have have confirmed that I have (as suggested by Sylvian) set
CONFIG_CMDLINE= "console=ttyS0" and have also tried "console=ttyS0, 115200"
(as my serial port is set to 115200 on the icecube board) without any
messages after arch:exit.
Below is what I see when I try and boot Sylvians 2-6-10-rc2 kernel.

At this point all output to the serial port stops but the board boots and I
can telnet to the IP address. It's not that important in the greater scheme
of things, just very annoying :-(
Below is a "printenv" from the icecube-uboot.

Any ideas????
