Hi,
Now my Embeded linux system is using the 2.4.18 kernel. And everything is ok including scaning the cramfs and jffs2 rootdisk.
But after I upgrade the kernel to be 2.4.20 and merged my modification to it, the rootdisk will not be recognized correctly. For cramfs rootdisk, it will say "cramfs: wrong magic". And for jffs2 rootdisk, it will scan each eraseblock and finally says no block is formatted.
I havn't modified any codes in linux/fs/ and they should work fine. So I suspect the function like "read_super" may not work for the old rootdisk? But I havn't seen any notice which says the "mkcramfs" and "mkjffs2" need to be rebuild.
Anybody has such experience? Looking forward to your feedback....
Thanks!
Best Regards! Feng Shen (Aaron)
