Doesn't make sense. The kernel just tries all registered filesystems
for the rootfs until one clames it. It means you either:

- don't actually have ext3 in the kernel or
- the filesystems actually is ext2 and not ext3

Try calling debugfs /dev/$ROOTDEVICE and then typing features, what does it
say?
