Ever get one of these? I wasn't doing anything but playing a game (goban), and BAM! Is this the prettied up kernel panic?

Could this have anything to do with 10.2.8?

[toconnor]

I would love to know too! I just got that tonight going from 10.2.4 to 10.2.6 on my new G4 laptop. It's a Rev A G4 17" that I bought the week before the Rev B's came out and it's been sitting in the box that long (been busy, on vacation, etc...).

Now that I'm getting the OS updates installed the first thing that happens is this lousy error message. Haven't found any info on it. Since the 10.2.6 update was the only thing I've done since opening the box I'm using the restore CD and installing a fresh 10.2.4 system and will either (1) try again or (2) take it in to the Apple Store and see what they say.

If in the meantime someone posts a reply about this message that would be great!

Not too happy G4 17" ...

Edit: FYI the code at the bottom of my dialog is FF:FF:FF:FF:FF:FF

[toconnor]

It's a kernel panic all right. See Apple Tech Note 107061.

Now, what to do about it?


Todd

[Brass]

Yes. That's a kernel panic.

Check the log to see what caused it.

*********

beauty isn't it? Anyone care to translate?

[wataru]

Unless you get them repeatedly, I wouldn't worry about it.

Possible sources of KPs:
Peripherals
Samba
Bad RAM
Bad motherboard
Bad karma

[Jerommeke]

well I have one more cause. Some time ago my NetBarrier files got corrupted, the agent was consuming CPU like molasses, and after some moving and editting of files, the machine simply gave a KP on startup. Badly programmed

[Eriamjh]

KPs are Apple's version of the "Blue screen of death".

[Grrr]

Never happened to me at all. Until fairly recently that is. Oddly enough, almost right after I got my iSight camera. I could not tell you if it is really related or not though.
It also happened 3 or 4 times in one day! However, I repaired permissions, and it never happened again with such regularity after that.

In 9-10 months, it's happened maybe only 7 or so times times on this iBook 600. So not enough for me to worry much about in my case.
But when it has happened, I have often not even been doing anything that could have provoked it. Unless leaving the iBook alone while reading a magazine counts..

[toconnor]

I've owned Macs since 1984 and this has to be my absolute worst experience with the OS. I'm on my 4th OS restore from CD and now the computer won't even boot from that. It kernel panics even with that. This sucks. A $3,000+ machine and you can't even install the original OS from CD. I just might have bad H/W, bad luck or both.

[apollo11]

Although I've had Macs for a long time my "expertise" is very superficial.

In your position I would reinstall with all peripherals disconnected, after "nvram" and "all" reset.

[toconnor]

I think the kernel panic after the last restore was due to the network cable being connected. There was an Apple tech note about that. Disconnecting the cable allowed the reboot after the 5th OS restore install.

So now that 10.2.4 has been restored I tried the update to 10.2.6 (and other updates) which have been failing quite regularly. The last time these either kernel paniced on reboot as well or threw me into the login screen and I could never login.

I guess persistance pays off because after the 5th restore to 10.2.4 had been installed I'm now able to boot AND have been able to install the updates without incident.

I will say, though, this has to be my worst experience with the OS. I have a CS degree and understand this stuff. I can't imagine what a new Mac user would be feeling at this point if they were me. Well, maybe I can...

Very unpleasent OS Upgrade Experience



P.S. I think I'll take a back seat when 10.2.8+ (or 10.2.9.whatever) comes out. I've had enough already...

[apollo11]

You raise an interesting point with the question of upgrades. I DO become ratty , short tempered and irritable when my Mac does not work. Now that 10.3 is out and I've only just got 10.2.8 to sit with my set up should I risk raised adrenalin and anxiety levels or should I leave alone? (If it ain't broke......)

Sounds like you have bad hardware somewhere in there. If your machine came with a Hardware Test CD, I suggest you run it. Also check the RAM.

[toconnor]

Booted off of the test disk and everything checks out. Sure doesn't give me the warm fuzzies, though. Hours worth of fighting the installs, kernel panics, etc... then all of a sudden it works. I too believe something is amiss but if I can't reproduce it now I don't know that Tech Support would be of any help.

it's probably the ram.

[vmpaul]

Only ever happened to me when I was running Virtual PC. That's right. Windows crashed my Mac.

Who would've figured?

That's bad hardware for sure. I have seen *one* kernel panic since 10.1.5, and that was on a Jaguar beta. I haven't seen *any* since 10.2 came out.

[ZackS]

I've had maybe 2 or 3 since 10.0 came out. It's kind of jarring when you're used to your system NEVER going down.

I've had less than 10 since MacOS X Public Beta. Honestly. And of those, only one was on 10.2.x, the rest were either PB, 10.0 or 10.1.

I don't know if I just have good computer karma, but OS X has been 99.9% stable for me since it was released. This is on hardware ranging from a Blue & White G3/400 (overclocked to 450), a 400MHz Pismo, a Dual 800MHz G4, a 600MHz iBook, a 1GHz TiBook, and now a Dual 2.0GHz G5 (less than 24hrs old).

So I seem to be having the same symptom, so I will ask my question and describe my situtation here.

I'm absolutely desperate to find a solution for an eMac that can't get past the login screen. My Mother-in-law is a switcher because she needs a computer that just works, and now she's been unable to use her computer for over a week ever since a java update. The worst of it is that she NEEDS to get a report done this TUE! Here's the situation:

The fully loaded 10.2.6 eMac (G4 800Mhz, DVD burner, 768MB RAM, etc) gets to the login screen and announces, �You need to restart your computer. Hold down the power button for several seconds or press the Restart button�

I�ve instructed her to do the following to no avail:
1) boot into single user mode, run �fsck �y� � segmentation fault after cataloging
2) Boot from install 10.2 cd run Disk Utility, Repair � repairs fine but Mac HD still says unmounted
3) Boot in safe mode � same restart at login screen
4) Boot into open firmware and �reset-nvram�
5) Reinstall from install CD showed nothing to install on at �select a volume�, so we were stuck before we got to any real install activity
6) Tried to reset permission in single user mode with �chmod 1775 /�
7) Moved some system preferences to backup files
8) Reboot with NO peripherals attached at all (no printer, floppy, keyboard, nor mouse)
9) Booted from Hardware test CD, ran all, but it reported no errors

Notable observations:
1) In single user mode, we can �mount �uw /� just fine and navigate to all of the key files, so the OS is in tact
2) /Library/Logs/panic.log and company do not show anything today (just some non-descript errors from a couple of days ago)
3) �su� to her uername resulted in �unknown user�
4) Once and a while, we can actually type in the user name, but the restart request comes up shortly after password is entered.
5) We absolutely CANNOT reformat the drive and loose data
6) Applecare has been less than helpful, cuz they won�t let her bring the eMac into the store for resuscitation
7) I will buy TechTool Pro or Drive 10 or ANYTHING that will get her back running, but I need to know this will work (and that I get TTP 4.0 w/o upgrade fee) before I plop down $50 more

Please provide any stop gap measure so she can use the computer to get her work done.

Already in your debt. ---Rob

Boot from the installer CD and do an Achieve and Install.

[llamapadeastR]

What is the option that I select when I boot from the installer CD and do an Achieve and Install? Do you thing archive & install materially different than install? if you recall I couldn't get the drive to show up when trying to install.

Possibly related ignorance, we have 5 restore CDs that came with the eMac, but we don't know exactly what to do with them. Any thoughts?
