Make sure your console terminal is plugged into UART0 and not
UART1.  You can do RedBoot from either, but the Linux console
is only on UART0.

I use "go" on the IXP-425 and it works just fine.

My bootscript looks like this:

RedBoot> fconfig -l
Run script at boot: true
Boot script: 
.. load -r -b 0x11600000 zImage
.. load -r -b 0x10800000 ramdisk.gz
.. go 0x11600000
