hah, there it is:

hmm, I just rebooted with "init 6" (doing reboots with the UI is
sometimes weirdly fast and doesn't seem to do a full reboot).
Hmm, any more ideas? I heard people reporting that they reformatted the
internal SD card ... how does this work if you can't unmount it? Can you
disable mounting it completely? /etc/fstab only lists /media/mmc1 (weird
because this is the external card).
Thanks,
Torsten
