Kernel panic from iPhone USB tethering

SOLVED!!!🙂😁 Trashing iTunes and re-download/install. No more kernal panics!!!

Now the problem is solved but I got a new problem: When the iPhone is tethering there´s not incoming calls? Anyone with the same problem?

Macbook Pro 8,1 Early 2011 13" i5

iPhone 4 32Gb 4.3.3

Really not.

Same Macbook but I've got a 3gs with same firmware.

Sorry.

iTunes reinstallation has helped me too. Very strange, but that worked!

This is what worked for me, I have a MBP 8,2 i7 2.2 with the firmware upgrade locked up. I rarely need to use 32-bit software but when I do, the button holding in the beginning 3 & 2 doesn't work since the EFI is locked. The easiest way to do this is through this commands. Run them, reboot, use what you have to use, run the 64-bit command, reboot, keep going with your life... Thanks for the solution!

I didn't trash my itunes but upgraded it to the latest version. Upgraded IOS to the latest version and installed the 10.6.8 update. No KP for me now. Hope it holds up..

This issue isn't limited to iPhone tethering, I've had the KP happen on iPhone tethering as well as when using 3G USB Modems while travelling abroad. Will try the 32bit trick and report back.

Yup, it's definitely an OS X thing. The 32bit trick worked with the 3G USB modem I'm using, I've been up and running for 2.5 hours now with no KPs. So the fix is definitely manual: Hold "3" and "2" while booting up. I'll return to the states and switch back to 64 bit.

Thanks all.

I use a USB laptop hub that has in ethernet interface. When I enabled the USB ethernet interface while booted in 64-bit, it caused the same kernel crash as tethering my iPhone 4. Interestingly, the solution of upgrading iTunes, trashing the iTunes .app file, then reinstalling iTunes fixed both the iPhone tethering issue AND the USB ethernet issue even though there is no obvious link between iTunes and the USB ethernet interface. I can boot in 64-bit with no crashes now.

Azinicus, you may want to try the iTunes reinstallation even though it does not seem to have a direct linkto your 3G USB modem. You might not ever have to boot into 32bit that way.

Reinstalling itunes defenitely solves Mac's kernel panic and some Network problem because in fact a program inside itunes bundle is in charge of comunicating with network devices( Bonjour!?) . thats why you have to install itunes to be able to connect and use apple's Network devices on your Windows PC (altought i think apple give away the program (bonjour!?) as a stand alone program as well)

Hi there, as this seems to be a hot topic, my two cents to second all the others:

I confirm that uninstalling iTunes and reinstalling from a fresh download solves this issue, with no need to boot in 32bit mode. I'm currently writing from tethered iPhone and everything is working, no kernel panic since more than 3 hours connection time.

- Uninstall iTunes (trash the iTunes application in the Applications folder)

- Reboot

- Download iTunes from apple.com

- Install iTunes (no damages to your library and preferences)

- retry tethering, it works

I have MPB 2011 i7 and iPhone 3GS 4.3.3.

Cheers.

@ilfra - major high-five from me (I've been trying to debug that for the last two weeks). You rock.

you're welcome.

Hello there:

I started getting kernel panic messages when I moved to India and started accessing internet using USB CDMA modem. The MBP will throw a KP while connected to internet with connectivity duration between 1mins to 1.5hrs. At first I was not sure if this was due to a OS X bug or a bug in the USB modem's driver. But I was lucky to have landed in this forum. I've booted in 32-bit mode and have had no issues for last three days. Right now I've been connected to internet for 3.5 hrs and counting. Thanks a lot guys! 🙂

I was trying to trash iTune and reinstall it to check for the second solution. But whenever I try to trash the iTune.app OS X gives and error saying this app is necessary for Mac operation and can't be deleted. Any help in how to trash the app and reinstall it.

I've a 2011 MBP i7, 4gb RAM and OS X Lion.

Thanks!

Lion! The above tips are for Snow Leopard (the thread was started before Lion was released) It seems that Lion won't let you trash iTunes.
