Sorry I don't have an answer... but chiming in to let you know you are not alone... and that I found your post while searching for a solution to the very same problem. Indeed, it makes me nervous to have the fans spinning so fast (and loudly) and not being able to bring it back from sleep.
If anyone out there has any idea, please help us.
This is a common issue with these G5's. When the system locks up, the fans spin up all the way by default because they are software controlled. The easiest solution (the one I use) is to not put the system to sleep ever. Theres no reason you HAVE to put it to sleep so its not going to hurt anything if you dont.
Hi, and a Warm Welcome to the Power Mac G5 Forum!
Well - some discussion of similar issues here
The logs that you can check for clues are listed there. RAM is often the Prime Suspect in Kernel Panic Cases as mentioned, along with other helpful suggestions, here
Please post again if you have any questions. Good Luck.
Thanks so much. Before reading these posts about kernel panic, I took the G5 back to the Independent Apple store this morning and left it. They may know something - they asked me what peripherals did I have connected - which I didn't understand the motivation for such a question. I do have a USB hub and a router.
But one question: I think repairing disk permissions was mentioned in one of the posts. Immediately upon loading Leopard, I did a check permissions and the system hung up. I was told by an Apple guy that I called that this was an issue with 10.5. Is it still an issue with 10.5.2 which I have updated to? i.e. can I safely try verifying permissions now?
thanks in advance
Hi. Haven't personally had any problems Repairing Permissions in 10.5 - except falling asleep waiting for it to finish...
You may get some 'benign' warnings, apparently
I did accidentally run 10.4 Disk Utility > Verify Disk on a 10.5 volume and got some strange results. Haven't tried that again; OS X 10.5 Disk Utility only now.
Regarding repairing permissions on an early version of Leopard - although we're off on a side-thread here I reckon - it was also ridiculously slow when I tried it - and I got a message after the 45 minute wait that was essentially a failure to complete. Can't recall the wording now. That's when I called Applecare and after being routed through a guy in India or somewhere, I got an Apple guy who told me about the issue with that early version of Permissions. I haven't tried it since.
thanks for your help, I've never owned a PC, I've been a Mac owner since I bought my 6100AV in 1994.
This was my first post on an Apple forum. I'm pleased with the response, and although my problem with my particular G5 is not yet solved, I have some things to go try. I'll be darned if I can find the "Helped" or "Solved" button options, so I'll just say here that I've been "helped".
This incident makes me realize that the modern Apple computer is one complex machine, and my little simplified analogies along the lines of "themostatic control circuit" might actually be laughable. Whatever the heck a 'kernel panic' is, it's not something that I have any remote knowledge of. So I think I will start seeing these forums as kinda like talking to my next door neighbor in the old days when I couldn't seem to get the carbs on the MGB set quite right. Thanks all
One may not have to use sleep ... but the G5 uses at least 125 W or so when it is running. Asleep it uses 0 W. (This according to my power supply display) Why waste the energy? I think the majority of people like the sleep savings for their electric bill and it is kinder for the environment too.
I have the most aggressive energy saver settings: screen saver 3 min, display off 4 min, system sleep 5 min. Except that under 10.5.2 it doesn't want to auto-sleep.
