Kernel panic - not syncing: VFS: Unable to mount fs on unknown-block(0,0)

Any ideas on this problem? I there any way to repair that FS?

I had the same probem when upgrading QtMoko a few days ago. Regardless of what fs image I flashed, I would get these error messages.

Completely erasing the NAND allowed me to re-install without problems. Of course, it means that your data will be gone. I did not find an easier solution, and actually had no important data on the phone. I followed more or less the steps for clearing bad blocks [1] and threw in an erase command somewhere. Unfortunately, I do not remember the details. The NOR bootloader offers a "help" command, however.

If there is a better solution that preserves the FS, I would be happy to learn about it.
