all my ext3 filesystems died - completely!!!!
started as a libranet 2.8.1, headed towards sid + extras
(yes i know)
had downgraded to a 2.6.1 kernel
not quite sure about state of X
left it downloading via jigdo-lite, with screensaver in open-gl random
on return - and a lot of 'bus error' in xterm a reboot
gave 'attempt to access past end of filesystem' on every ext3 filesystem
only the hdb ext3 partition, being using by jigdo-lite survived
e2fsck -b 8193 /dev/hdaxx xx=2 6 7 8 9 10 11
did not work
hda5 had /etc, which showed some very surprising filesizes.
