Hi,
I think may be your root file system is not properly set. You should format the
compact flash with the command: mkfs.ext2 -I 128 /dev/sdxx. Here -I 128 switch
is important because otherwise, new distros set the inode size to 256 by
default and the redboot can't read that. BTW I read this reason some where on
this group, I don't remember where, so, sorry I am not giving due credit :).
You should do the aforementioned steps if red boot can't find the kernel else
read on :)
You can try specifying the root fs location by having root=/dev/sdaxx iirc.
Another thing, I forgot to mentions is that when you compiled the kernel, did
you enable the modules for IDE ? CF card is connected by the IDE bus so make
sure that the relevant module/driver is compiled into kernel. If you used the
config file I supplied without any change then it should be compiled in by
default.
I don't know much difference between hda and sda but new kernel use sda whereas
hda is used by older kernel for the same device. So when specifying the kernel
location to redboot, use hda and when specifying the root fs, use sda because
this is where YOUR kernel will look for root fs.
Hope this helps
