Kernel Panics in Leopard

Hi All,

Just upgraded my MBP to Leopard and have had 3 kernel panics in the last 30 minutes. I have had my mac for a year and a half with no kernel panics whatsoever, and now 3 in 30 minutes.

My copy of Leopard is legal (purchased), and I don't have anything funky installed that should have caused this (i've looked in other threads). Leopard also boots very slow (around 4 minutes to usability) whereas under tiger i was working in 45 seconds. Everything just seems slower with lots of beachballs and disk activity. I chose to do an upgrade instead or erase and install, as I don't want to spend 3 days resetting up properly. Below is the report from my kernel panic, if anyone knows what the problem is, or what can be done to fix it, I'd be most grateful.

The problem looks like it is airport based. AS to the fix i dunno sorry but his may put you in the right direction.

I've turned my airport off and reconnected to my router via ethernet, so hopefully that will sort it out. It's not a great solution, as I've had to move my router into this room and away from a non-wireless enabled computer. Hopefully there will be a fix if it is an airport issue.

How did you install? If it was an upgrade, you may want to think about doing an erase and install + migration assistant from a backup or at least an archive and install.

It was an upgrade. I may try one of those options if the kernel panics don't stop. I was just being lazy and not wanting to spend 4-5 hours wiping, and reinstalling everything.

50 minutes total for me. Erase & install + Migration Assistant bringing over about 40gigs. When I did the archive and install its was 30 minutes complete.
 
Do you have this file /System/Library/Extensions/AppleAirPort2.kext this is apparently not use by Leopard and can be deleted/renamed. Might be worth a try.

But i,d go with an archive and install or even an erase and install to try and limit the possibility that it is software based. As your airport card could be on the way out..
 
I have the same problem running a 2.2 ghz MacBook Pro. I've read many other similar problems, so it's not the AirPort card going out like someone suggested, especially when I've never seen a kernel panic on this machine until after the upgrade.

Also, it's not azereus, I'm not running it at all when any of them happened, but it wouldn't surprise me if it helped instigate whatever it is.

What's more interesting is suddenly loading webpages will quit, and it won't panic until I hit the airport menu or go into the system preferences and hit networks... I have to hit something network related.

I did do the upgrade install, and I shouldn't have to do a complete from scratch install to have it work normally. I did do a complete backup in case I'd have to, but I'd rather not have to use that.
 
You can try tossing all the network related preferences, especially since the machine bombs when the OS tries to access those files.
 
Hmm, strange. I've had a few kernal panics occur from within Tiger prior to having Leopard; however, after installing Leopard I have yet to actually experience a kernal panic. So far, Leopard seems more stable to me.

I hope you get your problem fixed though, good luck!
:apple:
 
It just happened again, and I've been reading and it sounds like Azereus is a common culprit. I'm not running it, so I was thinking of network apps I have running, and I think skype may have been running each time. I'm going to experiment and see if not running that will fix the issue.
 
It seems skype must be having similar problems to Azureus, and I'm betting there's a few more apps out there that are having similar problems. I haven't been running Skype at all for the past few hours, and no kernel panic at all, but if I had been, I can pretty much guarantee by now I would've seen one by now.

If you're suffering kernel panics, closely examine the apps you had open at the moment, and single out with network related apps may be causing problems.
 
I just had my first kernel panic ever, and the log looks exactly as the OP's.
I think it happens when the computer goes into sleep mode and you are connected to azureus or the like, then when you wake up the computer it just goes to hell and you get a kernel panic free with hard shutdown options.

Going to try it again and see if I can repeat the process - I'm sure this is all software (including Leopard) related and not that any airport cards are going bad.

EDIT: I could never replicate the results so still don't know what caused it.
 
iMac G4 kernel panic related to USB storage devices

I am experiencing kernel panics on my G4 1.25GHz iMac that are related to USB external storage devices.

It runs fantastic all day long, until I plug in some kind of USB storage. It could be a memory stick or a USB hard drive - either one kills it in a few minutes.

No problem with FireWire drives, just USB.

Does this sound familiar to anyone else???
 
I installed leopard on an old 1ghz powerbook 12" and everything worked fine until I turned OFF bluetooth. Then the kernel panics came fast and furious. The panic log wasn't much help. Once I managed to turn BT back on, all is well again. There is a reason why you don't install OS's on production machines the day it comes out :)

Here is hoping to a quick 10.5.1!

Exact same symptoms here on a 2.2 GHz MBP also. Getting quite annoying.
