Hi

If you're really hard up and actually have to ability to play with this
machine, why not adjust the time to 6:57 (maybe a minute before it reboots) and
see what happens. You can do:

1# loop:
2# date >> <your favorite temp filename>
3# ps -ef >> <your favorite temp filename>
4# goto loop

at the command line. The temp file will get a little on the big side, but at
least you will have a record of everything that happened up to the reboot.
Hopefully, inspection of this file after will offer a clue as to the cause.
Just a suggestion.
