You tell us the machine has crashed with fBSD, and ask "why?". You then tell us that under L-RH5 it also 'crashed quite regularly', and then again with fBSD3.3 'it has crashed twice'. If it were me, I would be checking that there isn't a hardware fault before chasing software "faults". My first suspect would be memory. Can I suggest you power down the machine, remove all boards (including memory SIMMs), give the contacts a clean, and reinsert everything? Then see what happens. Another possible cause of errors; have you played with the jumpers for the CPU speed - i.e. are you trying to overclock the beast, or have you put a new (different) CPU in it, or perhaps the core voltage is set incorrectly? Just some ideas to toss around and think about. But, as I said, I'd be thinking "hardware fault" at this stage. hth, haxxa To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
