[SOLVED] "Error reading superblock on volume 'ubi:rootfs'!"

Hello,

I'm no Linux expert, and have a problem booting a SheevaPlug whose PSU I replaced with a new one after the original blew up.

Does someone know what is keeping Debian6 from booting, and what I could try?

Thank you.

Here's what U-boot says in the console:

Marvell>> reset

In case someone else has the same problem, reinstalling Debian on an SD card solved the issue:
