In case anyone wants to dig into this...
4.7-STABLE #0: Mon Dec 23 15:41:17 CET 2002 using softupdates.
/dev/ad2a is a 120GB hard drive, 96GB were in use. 75 of these 96GB were
rm -rf'ed. The rm command returned quickly since the 75GB were stored
in few big files. The box crashed during the delayed softupdates writes.
The kernel and core are available for debugging... I can also do simple
debugging if someone tells me what to do :-)
