Anyone suffered a Kernel Panic shutdown?

Just interested if anyone has suffered a shutdown of their 4s due to a kernel panic? Had one happen today whilst my 4s was in standby resulting in the phone powering down and being completely unresponsive to power switch and dock connector power; only holding the power and home button down together brought it back to life.

I assume that this could either be a software or hardware issue - guess I'll just have to see if it happens again before contacting Apple.

Crash report for those interested

I've seen other reports like this, it's related to version 5.0.1.

The new update should be out any moment now....

My second 4S did this but no crash report. Now on my third due to intermittent earpiece problem.

I get/got them frequently, often at least one per charge cycle.

Typically they're called (in Diagnostic & Usage) "<date>-<time>.panic.plist" and "ResetCounter-<date>-<time>" and go together.

I did find turning off my wifi connection and only using 3G seems to help alot, as they were 2-3 times a day before. Gut feeling is its due to low wifi signal, or moving out of range of any registered wifi networks, and then it's trying to reconnect to something-anything furiously, possibly overheating (iphone is always warm after a crash), and then crashes :confused:

A workmate with a 3Gs(?), who was completely fine pre iOS 5.x, also gets crashes, but not as many as me i think.

Battery is fine, but i'd like this panic-crashing fixed, then i'd be much happier with the iP4s

I had this on my first 2 4S's and had them both swapped out at the Apple Store. It was happening about 10 times a day.

3rd one is running fine.

Well, I've gone through a re-charge cycle since my crash (went down to 2% before I charged it) and so far everything is ok. I'm guessing it was s/w related; there was no excessive heat from the phone like other people had observed.

Anyone had a crash since 5.1?

I'm monitoring, but seems better in the last few days...

Not had a crash since I got my 3rd 4S. Was stable after I got that one, no probs at all.

How you doing Stinj mate ? Got yer Vita yet ? ;)

So since then ^^^ i got fed up, and took my iP4s thru multiple telephone calls, who did the usual script, then eventually into the Regent Street Apple store. After a 33 minute wait (after my "Booked Appointment") the "Genius" said it needed a replacement, and gave me one there.

It seems MUCH more stable, so well worth jumping thru hoops if you think you're getting an unusual amount of shutdowns.

Holy cow !! Were you still having issues up to today ?? Thought I took long sorting it with half a dozen genius visits in a week.

I've been busy, and getting time to get to the store was not so easy. Also it was only occasional until 5.0.1, when it would crash twice a week at least...

Besides which, the longer one waits, but before a year since purchase, the newer your phone is ;)
