    Default Kernel panics Digital Audio dual 533

    HI,

    First post here, hoping for some input/help!

    I have a digital Audio G4 dual 533 running panther 10.3.9

    Lately I have been getting kernel panics, couple of times a day. I get the grey overlay screen with multi lingual directions to shut down etc.

    I ran a memory test using "Rember". Everything checked out OK via Rember. I re seated my RAM, reset the PMU (?, the little button), unplugged everything except the keyboard and monitor...still getting panic.

    I'm copying and pasting a few panic logs from Console..maybe someone can find a clue here. Any help would be appreciated.


    Thanks,

    Pete

    Looks like a failing CPU to me. How hot does it run? Stock DAs aren't known for their airflow.

    How long since you last cleaned it out, and checked the fans?

    M,

    Curious as to what you find in those documents that clues you in to this?

    ..I don't have a clue as to the significance of this stuff.

    How do I monitor the temp? Is there a util for that? I looked in activity monitor and couldn't find it.

    Thanks for the response, much appreciated.

    Look at the first line of those logs: it tells you the CPU is what caused the panic. I don't know a whole lot about interpreting those things, but it appears to me that the things farther down the list were calling on the CPU to do something, and the CPU was basically flipping them the bird.

    M,

    How do I check the cpu temp? Do I need a program for it and does the DA dual 533 have the hardware (probe of some sort) onboard to do it?

    Thanks

    There aren't that many temp sensors, so software is limited for the older PPC macs.

    Interesting that CPU varies between 0 and 1 in the log......which makes me think it is not necessarily one of the two CPUs. Could be heat, might even be firmware or software. Is there a firmware update for DAs? Will have to check.

    I always just let the thing run a CPU intensive app for a bit, then pop the case open to feel the heat sink.

    If it's too hot to touch or close to it it's likely a heat issue.

    Latest firmware for a DA is Boot ROM 4.2.8f1. You can check that in Apple>About this Mac>more info>hardware overview.

    Thanks for your thoughts guys...

    I don't know. I didn't really do anything except open it up, wiggle some stuff..even after that I got a few panics...now? Things have been fine for about a week. Not one panic. Though, I can feel that something's gonna happen..strange, right?

    Anyone ever have these problems just sort themselves out and disappear?

    If the machine has been subjected to a dusty/moist environment it could have dirt/corrosion on the contacts. Sometimes simply re-seating things will solve issues. Other times more drastic measures are required.

    My DA was absolutely filthy when I got it. It still gets a trip out to the garage every couple months or so for a session with the air hose.

    Dirt causes heat, and heat kills computers.

    Yes, thanks..In the past I've cleaned my machines when I have to open them up..install drives, memory, cards etc...The future brings more attention to this.

    My experience with all of my Macs has been that they always work..this is my first Kernel panic in 10 years or so? Something like that.

    I'm still waiting for the grey, multi lingual kernel screen but it hasn't popped up yet..thanks folks.

    The perforated screen behind the fan can really get clogged up. You'll have to remove the fan to clear it. If you've never done that, it might be worth checking out.
