    What are the specs of your G5? What does the label say? Do you have any upgrades like memory or graphics card?

    Hmm... Well, dual 1.8, dual 2.0, or dual 2.5, I think (PowerMac 7,3).

    Do you have any PCI cards in there? It could also be an audio or networking device maybe unplug them and try again and see if it panics then.
    Do you have a USB networking device? Check it. I would bet that's your problem.

    Guy had almost the same panic.

    Talking about the dependencies of course - different OS, I think. Tiger compared to Leopard.

    KPs are usually a hardware issue. The biggest exception is Flash. Make sure your cards and chips are properly seated, then do a pram reset and repair disk permissions with Disk Utility.

    2.3 ghz processor
    1 gb ram.
    i have a belkin wireless little usb thing hooked up for my wireless internent.
    and i am using a m-audio mobile-pre to hook up my studio speakers through usb.
    I have a oxygen 49 keyboard through usb not midi,
    and my normal stock keyboard hooked up through usb,

    the computer comes with three build in firewire ports but i dont use them.

    ...i notice it happens alot when downloading a torrent...maybe it does have to do with the enternet.

    It's probably your USB wireless adapter. Have you considered buying an Airport Extreme card for your G5? I believe the dual-cores had a combo Bluetooth/Airport Extreme module to plug in.

    Try unplugging all your peripherals and see if the kernal panics continue. Try to single out each device by only unplugging one each time.

    Apple had a similar kernel panic with their Airport driver, tended to happen when the network burst transfer hit near the limit ... then it would overflow (or something similar).

    Keep your USB dongle unplugged. You most likely need a new solution to connect to the internet, such as a completely different adapter/Airport/wire.

    If it was your RAM, you wouldn't be able to max out the CPU for a long time, if you could boot at all.(there's an app out there done by the same guy who does TempuratureMonitor, IIRC, or render/transcode some video, w/e). Furthermore, I bet we'de see in the KP something about DIMM failures and the specific addresses where the error occurred.... I think.

    Run memtest for your RAM. There's a post of the file attached to post #1 here. I was just able to run it as an executable for quick 'n' dirty, but the single-user boot mode is the way to go.

    Since your machine is picky about wireless, I would recommend something from OWC to replace your current solution.
