Kernel Panics

NikFinn · Dec 30, 2011

Hey guys,

I've never had any problems with kernel panics, but recently I've had 5 or so in the past week. They seem to happen most often when I put the screensaver on.
I attached the detail log, if anyone has any ideas that'd be great.

Code:

Fri Dec 30 14:09:33 2011

The first thing I'd do is test your memory. You might have bad RAM. Have you added memory recently?

imac wannabe · Dec 30, 2011

I'm new to the Imac and when I first got mine (Late 2011) it was perfect. I then did the update to 10.7.2 and I had 5 or 6 KP's in a day 20 or more in a week. I eventually turned off the wifi and hard wired it and I've never had another since. Not scientific...just saying

Ran Remember and all tests were passed there.

They've all been under 10.7.2 for me, the only change was updating the EFI but I have had them under with and without that update.

Anyone else have any other possible causes?

What software do you have installed - I've just had a look through the information you provided in the original post there are many third party extensions listed that might have caused problems when you upgraded to 10.7.2 - check through all the software you have installed ensuring that you have the absolute latest version installed and read any release notes that might outline incompatibilities with 10.7.2.

I see exactly one non-Apple driver listed. What information are you looking at?

derbothaus · Dec 31, 2011

What is "com.quark.driver.Tether64"?
Tether + USB unload may be the culprit.
What screensaver are you using and does it ever happen without screensaver on?

derbothaus said:

That's for a program called Tether (iPhone tethering, quickly pulled from app store). But I've only ran it once to make sure it worked. So it would be strange for that to be the culprit.

The screensaver I'm using is called WorldClock, I haven't noticed it without screensaver as I always turn it on when I leave the room, and when I come back I see the kernel panic screen.

LPZ said:

I hadn't until now. I noticed they both have similar kernel backtraces. Does the backtrace mean this is what potentially caused the kernel panic? If so, it might have something to do with me running transmission for downloading things, as I think that was on each and every time it happened but can't be certain.

If the kernel extensions in backtrace hints at what is causing the problem, this could be the best way to follow what causes the panics, right?

LPZ · Dec 31, 2011

Based on my reading of your panic log and the thread I linked to, I think you should try the following: temporarily disable AirPort and use a direct ethernet connection instead. If no panics occur, then perhaps the problem is due to a flaw in the AirPort driver. In any case, this seems like a logical test to try.

A Google search on "com.apple.driver.AirPort.Atheros40(501.58.1)" yields a lot of panics on iMacs occurring in the last two months or so.

MatthewAMEL · Dec 31, 2011

If you Google, 'Tether64' you will find LOTS of Kernel Panics associated with it.

It is loaded at startup regardless of if you want it running or not or how many times you have run it. You could rename it so it would not start depending on how it was written. Usually launchd takes care of these things and can easily be changed via .plist file.

Try a standard screensaver and see if it happens. Best thing is to remove the 3rd party stuff first. Need to know if it is an OS X issue or 3rd party as 3rd party is the easiest to stop using.

Generally yes. But you can't just read the backtrace and viola, you found the culprit. Sometimes it slaps you in the face and sometimes it hints at the issue.

The backtrace seems to indicate that the instruction that triggered the panic was located at 0xffffff7f80f2e5fe, which lies within here:

com.apple.driver.AirPort.Atheros40(501.58.1)[13BE9AFD-5158-3CD9-B5E9-AAF5BE3062B4]@0xffffff7f80e78000->0xffffff7f80fb7fff

What am I missing? Why are you giving the advice you are giving?

Because you're assuming that each extension is some how isolated and does not impact on the surrounding extensions loaded. Given past experience it is more likely for a third part extension to cause problems than one bundled with the operating system.

FrankHahn · Jan 1, 2012

As indicated in the previous posts, the KPs were highly probably caused by com.quark.driver.Tether64.

The OP's panic log clearly indicates that a specific instruction in com.apple.driver.AirPort.Atheros40 triggered the panic, by attempting to write to a non-present page in memory.

You have to look around the issue as well as the direct event. Tether64 could very easily be calling the Atheros40 driver that causes the backtrace. But I agree OP needs to use LAN cable and test as well.
OP needs to weigh in. Waiting.

I doubt these panics are related in any way to Tether64. There appears to be a bug in com.apple.driver.AirPort.Atheros40. But let's see if the OP fills us in.

You're probably right. OP is MIA. Hoping it does have something to do with 3rd party as the atheros40 bug does not appear to have a fix aside from using the ethernet port only and walking someone through .kext replacements is "challenging". How portable is an iMac anyway?

I've been here, just trying to make sense of it all. I haven't been home, but when I should be tonight. I'll try uninstalling the tether program (as I only tried it out to test). I don't think I'll be able to use an ethernet cable as my router is nowhere near my iMac.

You can verify that com.quark.driver.Tether64 has been eliminated by your efforts by entering

Code:

kextstat -b com.quark.driver.Tether64

at the command line in Terminal. If it's gone, you should get only the output

Code:

Index Refs Address    Size       Wired      Name (Version) <Linked Against>

If it's still loaded, you'll see a second line below that giving information about the kext. Here's an example, using a standard Apple kext:

Code:

kextstat -b com.apple.Dont_Steal_Mac_OS_X
Index Refs Address    Size       Wired      Name (Version) <Linked Against>
   90    0 0x1327000  0x7000     0x6000     com.apple.Dont_Steal_Mac_OS_X (7.0.0) <89 7 4 3 1>

MrNomNoms · Jan 3, 2012

Just did some searching:

http://www.blackberryrescue.com/network-adapter-not-found-mac

My superiors have confirmed with Lion there is some sort of issue using Tether, and they are working as fast as possible for a resolution to that situation. jeremy.h.crawford could I have you send an email to help@tether.com for more troubleshooting at this point please?

I really have to question why the individual just doesn't use the built in tethering.

Considering the severity of panics maybe you could move it closer. Unless you are now getting used to them.

Seems unrelated to the OP's problem. Didn't see anything in that thread about kernel panics.

I'm now convinced this is a driver bug, and has nothing to do with com.quark.driver.Tether64. Please see this thread.

I removed a few kexts files (which I found the location via some google searches) and of coursed deleted the app, but I still get something when I search using the terminal command attached.

I'm not sure if you're referring to blackberry tethering or iPhone tethering, but I bought Tether because it was a one time fee of $14.99 vs the $20 or so a month through AT&T or Verizon.

I haven't had any in some time, and moving it isn't really an option. I'm hoping to find the last strands of the Tether kexts and hopefully be panic free.
