If you're booting from CF I believe it's to be mounted as /dev/hd{x} not /dev/sd{x}.
So if /dev/hda3 is your root fs, try changing your cmdline to
console=ttyAM0,115200 root=/dev/hda3
OR, if using as ramdisk
console=ttyAM0,115200 root=/dev/ram0
I've just solved a problem similar to yours booting my 7260 to an SD card.

Hi,
I have compiled the 2.6.27.4 kernel after applying matts' patch. When I try to boot from compact flash with commands:
load -b 0x00218000 -m disk hda1:/boot/vmlinux
exec -c "console=ttyAM0,115200 root=/dev/sda1"
I get the error: kernel panic - not syncing: No init found
Earlier I have tried to compile 2.6.21 kernel but it was giving the error: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0
