I added the mtdblock entry and, yes it seems to have helped. The kernel however now returns... mtdblock_open ok mtdblock: read on "initrd" at 0x400, size 0x400 mtdblock: read on "initrd" at 0x0, size 0x1000 mtdblock: read on "initrd" at 0x1000, size 0x1000 mtdblock: read on "initrd" at 0x2000, size 0x1000 mtdblock: read on "initrd" at 0x3000, size 0x1000 wrong magic VFS: Mounted root (jffs filesystem) readonly. Ive looked at the kernel code, and it looks like it doesn't support a cramfs system only jffs (ROM systems anyway). Can anyone confirm whether Linux 2.4.4 supports cramfs for root file systems?

Maybe your problem is similar to mine. My solution: 1) in kernel file init/main.c 's dev_name_struct, add entry for "mtdblock", 0x1f00 if it's not there already. 2) in ppcboot =>setenv bootargs init=/linuxrc root=/dev/mtdblockx Hope this helps.
