It has happened yet again. Current idea is that the little tab that holds the 'internal' SD card in slides free, causing intermittent contact. e2fsck crashes with seg fault. Might like to debug e2fsck, but am reformatting card. At least there does not seem to be anything wrong with the card.

The n800 does not boot with a corrupt internal SD card. What does it use it for? Well, it *might* use it for VM, but even if i've turn that off, it won't boot with a corrupt card. That means i must at least format it in the external position. Wasn't there a possible bug having to do with large SD cards (16 GB in this case) and the external position? Or is that fixed? I've reflashed with the latest.
