No, it didn't test out fine, apparently. A FreeBSD `make world' is commonly agreed to be a much better hardware test than anything you else. Unless your page faults repeatedly appear at similar addresses, all this smells like bad RAM. You need at least to provide us with kernel stack traces if the fault is repeatable at a single spot. I will eventually change the status of this PR to `feedback', since it's plain useless for us in the current state. The information presented is simply too weak to track anything by it. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
