Good luck! We have kernel panics on some (but not all) of our G3 B&Ws and have had since upgrading to Panther (10.3.1 onwards). Seems that if you restart using the Terminal that there is no kernel panic, which is strange, say after doing a terminal software update. We just leave these problem G3s turned on now.
