Kernel panic from iPhone USB tethering

i had tried upgrade my iPhone 3GS from 4.2.1 to 4.3.
but it seem the issue didn't solved.
Unfortunately Personal Hotspot(wifi Tethering) wasn't support on iPhone 3GS!

I got the same problem with my brand new Macbook Pro 13" 2011. When tether my 3GS with usb, it randomly crashes (Kernel panic). But no problem if i tether via bluetooth.

Already posted here before. Anyway, upgraded my IPhone 4 to 4.3. I have Snow Leopard 10.6.6. Still get Kernel Panic.

Kernel panics. Sometimes right after bootup but most of the time right before starting an SC2 game.

Kernel panic while iPhone USB tethered and typically download larger files, especially Mail with attachments. Seems to work while using WiFi tethering. AppleCare did not have anything to offer, just try erasing HD and reloading OS. Still same kernel panic after OS reload. Frequency increases over time to a point of unsuitability. I guess only option is not to use Iphone USB tethering.

I have a MBP 17 2.3ghz w/ 8GB ram I am also getting constant kernel panics when I tether from my Iphone via USB. Its very frustrating. I did all the resets and re-intalls. I have been on the telephone with Apple care and the person helping me states this is an isolated problem. Same thing occurs all the time. I'm so close of returning it.

I too have the same problem with my brand new MBP. The only solution I found after updating to iOS 4.3 and while they fix the issue is to use Personal Hotspot. I disabled in Network Preferences the iPhone network interface by putting it in inactive mode so that when I plug my iPhone with tethering enabled, it doesn't use the USB interface. I then select my Personal Hotspot.

This works for me at this point but I sure hope they fix this **** problem.

Same issue here with my new MacBook Pro received just last week. Everything works fine until this morning when I tried the new personal hotspot feature with my iPhone 4 with iOS 4.3 downloaded just last night. Without the personal hotspot via USB everything now seems fine.

Strange though that my much older MacBook (the model with silver keys) works without any hitch with the tethering feature.

Connecting the iPhone via USB (tethering) causes a Kernel Panic. Does not happen with my MBP 2,4GHz i5. So it has to be a problem with the new 2011 models?

Same here...

It seems like kernel panics get more frequent when using Parallels 6 in shared network mode. For sure I can confirm that download big files almost always causes a kernel panic.

We have something like 53 posts on this subject now. And I've read about the same problem in many other forums. One would think that this should be a big enough issue to be addressed by Apple!?

Can confirm my new MacBook Pro 10.6.6 has kernel panic with tethering when Kernel is in 64-bit mode but NOT in 32-bit mode. I have had 6 kernel panics in the last two days trying to use 64-bit mode kernel and USB tethering. All reports sent to Apple.

I was interested/surprised to note that running the 32-bit kernel does not preclude other applications (OSX native or third party) from running in 64-bit! This strikes me as a good thing - parallels virtual machine engine running in 64-bit mode is MUCH faster!

In my hands this has nothing to do with iTunes or downloading a large file as previously reported here. I am using 32-bit USB tethering from iPhone 3GS right now to submit this reply. I have mail, safari, parallels 6 desktop, filemaker pro and citrix online plugin running without problems. In 64-bit mode kernel this would have undoubtedly caused kernel panic. MBP is also syncing with MobileMe and I have USB hard drive plugged in as well. So far so good in 32-bit mode! If I get a kernel panic in 32-bit mode, will report back...and submit to Apple.

I hope this gets fixed soon...

Confirming as well.
MacBook Pro (10.6.6), three days old, and seven Kernel Panics in two days, each time when tethering from iPhone 4 (iOS 4.3).
Doesn't matter if I use Safari/iTunes/any other application or not, still happens. Spoke to Apple Support (SWE) this morning, apparently unaware of the common problem.

Well,
I also switch to 32bit mode and like Richard, I'm amazed that every 64 bit application does run in 64 bit mode. At this point this is the best solution while they fix the issue.

Can anyone please explain how I switch from 64 bit to 32 then? 🙂 Or is it complicated?

Here you go:


On-disk setting (persistent)

To select the 32-bit kernel for the current startup disk, use the following command in Terminal:

sudo systemsetup -setkernelbootarchitecture i386

To select the 64-bit kernel for the current startup disk, use the following command in Terminal:

sudo systemsetup -setkernelbootarchitecture x86_64

You then need to reboot.

Note: This setting is stored in the /Library/Preferences/SystemConfiguration/com.apple.Boot.plist file and will take effect every time you start up from this disk. If you start up from a different disk, the setting on that disk, or the hardware default, will take effect.

Manually

You reboot and hold either "32" or 64" keys to start in one or the other.
