Kernel panic from iPhone USB tethering

I had a kernel panic this morning. I'm not sure, but it reads as if it was something to do with my using my iPhone 3GS as an Internet Tether through USB [only, I turned off bluetooth]. It was the only different thing that I was doing at the time.

Anybody know if this is a known error?

The relevant detail of the panic is:

I've been getting KP's lately, too. Since I've updated to iOS4 on my iPhone 3G, when I tether data from my iPhone to my MBP 13" via USB, I randomly get panics.

I've isolated this down to USB tethering as well, because tethering via bluetooth doesn't cause this to happen.

I've done a restart to my iPhone (proper shut down AND force reboot) and still get random kernel panics by USB tethering.

Kinda annoying, especially since connecting to my iPhone to tether via Bluetooth is flaky at times in OS X.

I'll be sure to post what info it dumps out next time I get this error.

I would also like to confirm that this only occurs in 64 bit kernel mode, which is the DEFAULT mode for the new MBPs. Apple phone techs are clueless about this.

They really shouldn't enable by default a mode which crashes easily and consistently. I've set it up to boot into 32 mode by default now, and I haven't gotten a KP yet.

I can confirm this. 100% success rate of a Kernel Panic when tethering with an iPhone 4 (IOS 4.2.1) with 64 bit Mac OS X running 10.6.6 fully updated.

I can confirm this happens on the 2011 MBP.

Same problem here on a 2011 MacBook Pro 15" Quad i7 2.2 GHz running the 64 bit kernel with an iPhone 4. Bluetooth tethering works, but unfortunately the limitations of bluetooth cap the speed at about 200KB/s. I was getting 500KB/s over USB. Never had that problem with my previous MacBook Pro (non unibody Core 2 Duo), but it was running the 32 bit kernel. Is this problem fixed in the 10.6.7 seed or the Lion seed?

Same here:

MBP 13" Early 2011 running 10.6.6. with 64-bit Kernel
and an iPhone 3G running iOS 4.1

produces Kernel Panics.

SAME!

Hope it will had fix asap

Same here!

Kernel panics with a 100% success ratio on Macbook pro 8.2 when tethering over usb from my iphone 4 IOS 4.2.1 . I 've just updated my Iphone to 4.3 and now I am tethering over personal hotspot which is working like a charm. Hope that Apple fixes this matter soon.

Mar 11, 2011 7:34 AM in response to Fustbariclation

My MBP is also experiencing this problem. Same deal, iPhone 4 running the latest update > causes the MBP to run into a Kernal Panic. I'm avoiding the genius bar as I've a friend who's also having the same problem with no resolution at apple.

C'mon apple get on this!

Just got the same message while tethering my iPhone 3GS and my new 2011 13" MBP.
Seem like these errors are more than coincidences?

Mar 11, 2011 4:57 PM in response to Fustbariclation

I also experienced this issue on two different Macbook Pro 6,2 with 64bit Kernel with different iPhones (4, 3GS).

I issued a bug about this in Apple's Bug Reporting System on March 4th, until now I haven't got any reply to it.

Mar 11, 2011 9:03 PM in response to jonaas

Can confirm.

2011 Macbook Pro 13" 2.3 GHz i5
iPhone 4 iOS 4.21
Tethering via USB
As of now Bluetooth has no problems
For me though there seems to be no correlation with how large the file its trying to download.

Damnit Apple, this has been a problem for nearly half a year.

Oh, MAYBE iOS 4.3 solves it? I mean there supposed to be a major update for tethering and personal hotspot with the new update no? I'll try it when I get home and DL the update. Get back to this later.
