ios 5 or ios 5.0.1 on Iphone 4s crashes - kernel panic

I bought one of these iphone 4s 64 gb s on the day they have been released and since then I am having some phone crashes.Phone is crashing and shut-down it self.I am not sure if it is a software problem or hardware but updating to ios 5.0.1 didn't fix the problem and I am wondering if anyone else having these problems.

Error log from the iphone 4s is something like this:

I searched for the source code file at the point of crash and surprisingly found that it's one of the open source libraries of apple:

The source code of the crash file is here:

http://www.opensource.apple.com/source/xnu/xnu-1699.24.8/osfmk/vm/vm_map_store_rb.c


If I go to line 80 as it stated in the crash log the function there is something like this:


boolean_t vm_map_store_lookup_entry_rb( vm_map_t map, vm_map_offset_t address, vm_map_entry_t *vm_entry)
{
struct vm_map_header hdr = map->hdr;
struct vm_map_store *rb_entry = RB_ROOT(&(hdr.rb_head_store));
vm_map_entry_t cur = vm_map_to_entry(map);
vm_map_entry_t prev = VM_MAP_ENTRY_NULL;

while (rb_entry != (struct vm_map_store*)NULL) {
cur = VME_FOR_STORE(rb_entry);
if(cur == VM_MAP_ENTRY_NULL)
panic("no entry");
if (address >= cur->vme_start) {
if (address < cur->vme_end) {
*vm_entry = cur;
return TRUE;
}
rb_entry = RB_RIGHT(rb_entry, entry);
prev = cur;
} else {
rb_entry = RB_LEFT(rb_entry, entry);
}
}
if( prev == VM_MAP_ENTRY_NULL){
prev = vm_map_to_entry(map);
}
*vm_entry = prev;
return FALSE;
}

I have no idea why the cur equals to VM_MAP_ENTRY_NULL but this crashes my iphone 4s 64gb once every two days or something which is obviously not good.

I have a similar problem. My problem however is related to line 118 (NO ENTRY TO DELETE). Crashes every few days. I'm inclined to think it's related to either the backup I restored from or the glass backplate which I replaced with a metal backplate. Any progress on fixing it?

I have the exact same stack trace and just got shooed out of the Apple store today after he reset all my user settings. He said it was a software/settings issue.

It's been happening since I got my 4S 64GB the day it came out after upgrading from a 4. Today's reset did not help.

I had the exact same thing happening to my day-it-came-out iPhone 4S after upgrading, and moving my backup, from original -> iPhone 3 -> iPhone 4. This was happening on iOS 5 and iOS 5.0.1. Despite the issues I was having, I wanted to wait until 5.0.1 came out before making judgement in case it was just an early software glitch.

After it continued to happen on 5.0.1, I had a hunch that it wasn't software related, because I felt that the forums would be lighting up with issues from fellow upgraders.

The 2 things I noticed in the kernel panic were: 1) UserEventAgent and 2) configd

Based on that, I figured a full settings reset might make sense. Unfortunately, it didn't help. So, I just got the hardware replaced 2 days ago and I've been good ever since.

I hope this helps someone else having the same issue and/or Apple figure out what the seemingly hardware-related glitch is.

When you start installing iOS on your iPhone then you should choose iOS that compatible with the system of your iPhone and for iPhone 4s, I think it is better if you choose iOS 5.

how can you enable a windows firewall rule for a dynamic dns name or dns address

in a windows server sometimes you just need to enable some ports on your firewall to your dynamic dns address.(such as RDP , FTP , etc..) It is cumbersome when you do this manually every time your ip address changes.Why not update your server automatically every time when your ip changes based on your new dynamic dns update ? 1 ) just create a powershell script like this: $ip = [System.Net.Dns]::GetHostAddresses(" your ddnss address ").IpAddressToString Set-NetFirewallRule -DisplayName " myrule " -RemoteAddress $ip Put in your ddns name like: xxx.dydns.org , no-ip etc.. Create a firewall rule and define ports etc. before hand and name it either "myrule" and use the second line as it is ,or change the "myrule" to your rule's display name on advanced firewall app on windows server. 2) name it as firewall.ps1 3) and than create a task on task scheduler like this: command to execute: powershell -executionpolicy remotesigned -File

Bose speaker hack (companion 5) to turn on/off automatically

Image
I have on of these Bose companion 5 speakers. The problem with it is when you don't use it actively it turns off to save energy, next time when you want to use it you should press the button on the control pod to activate it. This is a problem when you use the aux cable as input as a standalone speaker. Solution was not the easiest but it's a quick hack.  I designed a system where when an audio detected from the aux input , it Bose speakers turn on automatically to green. Here is how it goes: Tested the pins of the control pod, looks like there are different voltages supplied to the control pod. It all ends up here because I couldn't find how the audio transmitted to the main device.I had to find a way to open this: There were 2 screws at the back. It turns out it uses the same screws apple uses T5 When I opened it the top came off You need to unscrew these as well, and you have to cut the wheel, (you can glue it ba

how to IR remote control via wemos d1 (esp8266) & mqtt & sonoff tasmota

Image
I used wemos d1 and connected like this: (source: https://github.com/witnessmenow/ESP8266-IR-Remote-Example) Receiver module is tsop38238 Transistor :  2N3904 (without it , LED is not bright enough to send IR signal) Led diode is Infrared diode. I used this library with arduiono :  https://github.com/markszabo/IRremoteESP8266 From examples  with this one:  IRrecvDumpV2.ino you can capture IR codes from the remote by pressing the remote button and it will be captured  and it generates codes like this:
