failed to mount root after upgrade

[replabrobin]

I upgraded my sheeva today to the latest kernel. After the upgrade I'm getting boot errors related to ext4/3, but my filesystems on an SD card are both ext2. Does the kernel not support ext2? I checked the SD on another computer and it is fine (at least according to fsck).

Thanks pepedog, that was the problem. Hopefully others will see your answer.
