Dear friends,

i am unable to boot my ixdp425 boot with RAM disk support. I have compiled 2.4.19-rmk7-ds1 kernel with RAM disk, initrd, ext2 file system support. i have loaded my compressed RAM disk into flash too.

while booting the kernel i got the following errors.

## Booting image at 50040000 ...
