Sorry I had no time to play as it is an "in-production" laptop and had
to be functional fast so I currently have no way to reproduce the fault.
 Redirecting output would require another kernel and the device has no
serial or network port :-(.

Maybe extracting metadata (debugreiserfs -p) would have been good for
debugging but at that point I had nowhere to store it. If this happens a
second time I will find a way to save it.

As there were only a few fs errors reported by fsck probably looking
over range/overflow checks in the code regarding used space/block size
might give a hint...

Have a nice day,
