I get these errors after installing pdaXrom, everything seems to be ok, but I was wondering about these errors...

cramfs: wrong magic
FAT: bogus logical sector size 381

Thanks.

Kernel tries to mount root filesystem (/dev/mtdblock2), but it doesn't know it's fs type. So it tries a few (cramfs, fat), but fails. After trying JFFS2, it succeeds and starts /sbin/init. So everything is ok.

Cant the root file system type be specified (kernel paramter) or even int he code. Why make the kernel do more work?

"rootfstype=jffs2" should probably do it - we use it on c7x0 with 2.6 kernel

same error on tetsu's kernel, bad majick too. Where would you make this change, some config somewhere, or is it a pre-compile option?

Does anyone know what means this "error" during boot process :
"Warning : unable to open an initial console"

Thanks.

it means that /dev/console is missing on jffs2 rootfs. You can create it as a link to /dev/tty1, if this message bothers you.
