Ok. I've been suffering form kernel panics ever since I upgraded from 10.4.11. Sometimes three a day. I have, as you might expect, tried everything including a reinstall of 10.5.1 followed by the 10.5.8 combo updater. But still the problem persisted. So I began removing or disabling items one by one until the kernel panics went away. Then I reintroduced them until a KP struck. And guess what, it turned out to be the screensaver. No doubt about it. I've tested and retested it. With any Apple screensaver on, a KP will eventually strike; while I'm browsing, working or even while I'm away from the Mac. There's no pattern that I can discern, but I'm now absolutely sure that I've traced down the culprit. Could this be the hidden cause of so many reported KPs? If so, it's a hidden menace. Fortunately, you can switch off the saver and simply set your monitor to sleep after a period of inactivity. It's not ideal, but it's better than suffering multiple crashes every day.

    Kernel panics are more usually caused by hardware issues.

     

    What screensaver left over from Tiger are you using?

     

    What is a Kernel Panic?

    Does the screensaver get a mention in the crash log?

    http://support.apple.com/kb/ht2546

     

    Is it a standard Mac screensaver or a downloaded one?

    Definitely an odd one then. You could try running your Apple hardware test CD if you have one, just to check out the video card.

    I just saw your post while trying to track down kernel panic on my Power Mac G4 OS 10.5.8 (recently updated). The computer would run fine until I walked away and it went to sleep. I had screen saver set to never. I would get the KP when I woke the computer. I set the screensaver to come on now before sleep and no more KP's  I also went through the various hardware tests and found nothing. Although when I did get a KP the log seemed to indicate that it was Logitech control center that may be the culprit. I also set the computer to no sleep, no saver and there are no panics. I would have to agree that something about the sleep/saver interface is causing the problem and it only affects 10.5.8 on my machine. Other OS X's don't seem to have the problem. Any luck tracking this down? plist, etc

    I have the same problem on my PPC running 10.5.8.

     

    Have had two KPs in the last week, both times when I left the computer running for a while without using it, about 30 minutes each time.

     

    I have screensaver on but sleep was set to never.

     

    Any advice gratefully received.

    You might try disabling this non-Apple kext you have in there:

    Thanks for your advice, I tried that, or at least I unstalled logmein, but I got another one yesterday (KP), a few infact.

     

    In the end the machine refused to boot again, so I replaced the HD, still nothing.

     

    So I removed the RAM, some of which was recently added. One pair made it crash on startup, while the others worked fine.

     

    Strange thing is though, the orginal HD will not now work, tried hooking it up to an external reader, and while it was spinning it wouldn't show up on the desktop.

     

    To be honest, I'm hoping it was one or the either but find it a bit strange that both were a problem.

     

    I got the RAM from 'Mr Memory', firstly ordered 8gb (2x2) but only 4gb would show.

    Sent them back, got the new set to work but started getting the panics shortly after.

     

    Probably gonna just stick with the RAM I have in it now and look for my money back for the others.

     

    Also ordered a new HD and will do a fresh install when it arrives.

     

    Again I'd be grateful for any advice.

    Your RAM is prime suspect. Cheapest RAM often is.

     

    Stick with RAM from OWC and Crucial, both of which have a lifetime warranty.

    Thanks, appreciate the reply.

     

    The RAM I bought does have a lifetime warranty but I cannot vouch for its quality.

     

    Reason I went for this is simply because it's what was in the machine, just wanted to add to it.

     

    What do you think about the HD failing too then? Just chance?
