The whole system was hanging (Ubuntu). very strange: did a "lshw" not
being root. no idea what was going on. But we don't have to discuss that

not yet because i don't want to change any bit in this table right now.
at least i'll wait until my recovery program finished (about ~ 50% done)
toast seems to be invalid too. here some lines of the log:
