MacBook Pro 2011 USB Tethering Cause of Kernal Crash READ

Is this all mbp? Apple have offered me a replacement. If it's a firmware fix, I'll wait. Any ideas anyone?

Same for us on USB tether. I'm trying B/T now, we’ve only just connected via B/T and no issue thus far, will also try WiFi now I've read it works.... Which is the preferred option when considering speed/sync etc??

I'm new to Mac so 1st experience is somewhat questionable. Biggest issue for me I must admit is learning the different interface/system. Otherwise it’s very, very nice, a bit like driving a European car… I love iPhones/iPods too.

MBP 15" (2011)Intel Core i7 (2.0Gb), 4Gb RAM, 500 MB HDD
iOS X (10.6.6)
iPhone4 Ver. 4.2.1 (8C148)
Everything is pretty much fresh out of the wrapper.

FWIW I still havent been able to get the system to crash while tether via Wifi or bluetooth. Looks like my issue wasnt the external display at all.

I got the same issue on my 2011 MacBook Pro 15" while tethering with an iPhone 3GS. 😟

I have the same issue as you mentioned:

My MacBook Pro is 15", i7, and 2.2GHz. The rest is stock.

Both my MBP and iPhone 4 is up to date and I use AT&Ts $20 tethering.

My computers keeps asking me to manually shut it off..
I am gettting frustrated since I pay $20 for this to keep happening so I don't know wether
this is a AT&T issue or an Apple issue.

As soon as this

Same issue here. 2011 15" MacBook Pro. WiFi and Bluetooth tethering work fine. Kernel panic with USB tethering. Appears to be a 2011 MBP issue and not the iPhone.

Will wait for Apple to update.

Kernel panic on brand new 2011 13" MacBook Pro (stock) with USB hotspot tethering. OS X 10.6.6, iOS 4.3.

Here is my kernel panic in an effort to raise awareness of this issue. I will also call support:

Yes I have the same problem with USB tethering my iPhone 4 with my 2011 MBP 15" i7 2.2GHz
Both 4.3 updated.

I keep getting the gray curtain of death randomly at a minimum of 1minute intervals of accessing the web. Sometimes it will come far later, like an hour or two... but then sometimes you forget and when you work on something--all information is lost!

Please, Apple... fix this...

Same problem with a 13" MacBook Pro, running 10.6.6 and an iPhone 4 (OS 4.3 (8F190)). At first I thought it was problem with Firefox, then with Flash-Videos in general as it also crashed with Safari running instead of Firefox (usually it crashed while watching something on YouTube). But it might as well be some problem with USB tethering.
Anyway, thanks for the posting, I was already wondering whether my MacBook Pro was defective ...

So far this seems to be a software/firmware issue as we all have the new MBP 2011 and are using USB tethering when the system crashes. Even though the MBP's at my local Apple store would not crash when the Genius tried to duplicate the issue on similar units. But it also could be a hardware issue on a small percentage of units. Not likely sense it seems to be happening in different countries, unless they were all made in the same plant! Lets hope it's just a software issue that will be fixed with the next update.

Once again I had no problems on my MBP 2010 or my MBA 2010, all three connections work with no problems.

FWIW I see the problem periodically on my 2010 i7 2.66Ghz MacBook Pro. Same issue - doesn't happen with anything but USB. It happens enough that I've ceased using USB. I'm running 64bit kernel, btw.

I've had this computer for two days. I had no problems with the computer until this afternoon after I synced my iPhone and configured the USB tethering. My kernel panics have been happening since. Different from the posts I've been reading here, they've been happening despite my phone not being connected via USB (or bluetooth).

My iPhone 4 is not jail-broken and tethering is free from my ISP. I'm running iOS 4.3 (8F190).

I've deleted the networking options for the USB tethering to see if that will prevent the kernel panics...

Just remove the iPhone from your networking options in system preferences.

Removing the iPhone as an internet connection will prevent system crashes when plugging in the iPhone.

Tethering over Bluetooth and WiFi works perfectly.

Same Issue here.
