I installed Fennec and even though the installer completed just fine, I got the message "Memory - full" afterwards (I'm dual booting from the memory card). So now the icons of the main menu don't show up anymore, although everything else still seems to be working.

I rebooted into the flash card system and tried fsck on the memory card partition. While it did find and correct some corruptions, the menu still doesn't work.

I can ssh into my tablet; is there anything else I could try to fix this?
