Using the following kernel command line for both kernel versions: Kernel command line: console=ttyAMA0,38400 mem=128M ip=dhcp root=/dev/mtdblock1 rootfstype=jffs2 mtdparts=phys_mapped_flash:128K(u-boot),16M@0x2000000(jffs2),1M@0x1980000(cramfs) 2.6.14 does the right thing and boots the jffs2 partition. physmap flash device: 4000000 at 34000000 phys_mapped_flash: Found 2 x16 devices at 0x0 in 32-bit bank Amd/Fujitsu Extended Query Table at 0x0040 phys_mapped_flash: CFI does not contain boot bank location.

Stranger still it's looking for a linear cramfs which isn't even enabled in the kernel. physmap platform flash device: 04000000 at 34000000 physmap-flash.0: Found 2 x16 devices at 0x0 in 32-bit bank Amd/Fujitsu Extended Query Table at 0x0040 physmap-flash.0: CFI does not contain boot bank location.
