Unresolved Kernal Trap OSX 10.4.11...HELP!

The Mac Pro I've been using in the studio keeps having a kernal panic and shutting down to the black screen where I must hold down the power button to restart. I saved the error message upon rebooting and was hoping someone on here could shed some light on what's going on. I'm running OSX 10.4.11 on a fully upgraded Mac Pro with 16 GB of ram.
Here is the message as follows:

Understanding crash logs isn’t easy and it’s hard (sometimes impossible) to decipher the cause of the problem. Take a look at Apple’s Crash Reporter document at http://developer.apple.com/technotes/tn2004/tn2123.html Also look at Tutorial: An introduction to reading Mac OS X crash reports
http://www.macfixit.com/article.php?story=20060309075929717
Kernel panics are usually caused by a hardware problem – frequently RAM, a USB device or a Firewire device. What external devices do you have connected? When trying to troubleshoot problems, disconnect all external devices except your monitor, keyboard and mouse. Do you experience the same problems?
To eliminate RAM being the problem, Look at this link: Testing RAM @ http://guides.macrumors.com/Testing_RAM Then download & use Memtest & Ramber.
Do you have an Apple Hardware Test disc (the AHT is on the Install/Restore DVD that came with your Mac)? Running the Apple Hardware Test in Loop Mode is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics. If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. Looping On should appear in the right window. Then click the Extended Test button.The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure.In some cases, RAM problems did not show up until nearly 40 loops, so give it a good run.
May be a solution on one of these links.

Unresolved kernal trap

My eMac had been running well and doing as it should. Within the past few weeks it has started to freeze up with the screen shadowed and a message appearing in the center saying "Your computer needs to be restarted. Hold down the power button for a few seconds or press restart."
When I restart it asks if I want to send a report, which I always do. The report begins with the words "Unresolved kernal trap" followed by code. Once in a while it alters and begins with the word "Panic" followed by code.
It seems to be doing it more and more, now two or three times a day. It sometimes happens when I am in the middle of something and it gets very irritating.
Any suggestions as to what's causing it would be appreciated.

In addition to checking your eMac serial number against those in eMac Repair Extension Program for Video and Power Issues, see if the eMac's logs give any clues whether the problem might be with some third-party background process: Refer to What’s a kernel panic? for info on where to find the logs. Since eMacs running 10.5 are fairly rare, if you need help interpreting the logs, you can post excerpts from the logs in the Leopard forums to reach a large knowledgeable audience.

Unresolved kernal trap - can anyone decipher?

Following is the info after a forced restart. I don't know how to interpret this but am looking for advice from anyone that can. I suspect bad RAM although it checks out ok. I get numerous cursor hangs and occassional white on black text overlayed on screen (kernal panics?) many times while the machine is basically idle as ws the case in the example below. Thanks for any help that can be provided.

my comments to Apple:
Had a VNC connection going to a local iMac running 10.4.8 (17" G4 USB 2.0)
Had actually stepped away for supper and the PB was not really doing anything other than idling. When I came back to it, found the restart message.
I also have random hangs and occassional white on black screen overwrites with errors requiring restart.
Suspect bad RAM?

One week now with the Samsung RAM - no cursor freezes or kernal panics, and like others have indicated, the unit is running somewhat cooler as noted by temperature monitor.

More Unresolved kernel trap(s) - Hoping you can Help?

Hi All --
Hoping someone can translate some of these numbers to help me resolve this ----
I have run all disk utilities from install disk (repaired perms, verify & repair disk), Diskwarrior (found repeating japanese font errors), memtested (all o.k.), booted w/ one RAM then the other, swapped RAM around in slots. Have run Apple Hardware Test (O.K./Passed) and tried the troubleshooting tips @ thexlab.com... I am doing tests with no usb peripherals connected -- but do use bluetooth mouse & keybd in normal operation.... havent had probs in the past using them.
....But the freezes/panics continue. (some other crash logs @ http://discussions.apple.com/thread.jspa?threadID=1229276&tstart=0 )
I am running OS 10.4.10 - on a G4 1.25 Powerbook - 1.5Gig Kingston RAM
My fear is that the CPU is on its way out -- the RAM is less than three months old and tests o.k. - have swapped around as mentioned -- is it possible a slot isnt connecting properly?
I recently had a mother/logicboard replaced (lowslot failiure) & installed Logic 8 a few weeks ago.
Although KPs are usually hardware related, should I try backing-up and re-installing the 10.4.10 update? or run the /sbin/fsck command?
I am HOPING this is a file conflict... oh please!
(Below the panic codes is an mDNSResponder: ERROR -- its an online thing and cant quite figure it out - I dont think its related, although I'm getting a different I.P. address each time --- normal?)
Any help would be greatly appreciated --- many thnx in adv.
Cheers,
John.

Hey Dale ---
Thnx loads for the links ---- after i posted, i found your replies to others and the links.... doh - typical.
... yeah I wasnt sure if there were any code readers here that could help -- however! i 'think' i may have found a fix for my crashes/freezes/kernel panic (s)....maybe. they were occuring so frequently - i.e. about a minute after each re-start/re-boot - i've been getting hopeful as I havent had my P.B. go down after a day -- fingers crossed.....
I was worried it was hardware/RAM related as is usually the case with kernel things, but the RAM repeatedly checked fine, even after swapping around, using one then the other, etc...
I followed KJK555s' advice @ http://discussions.apple.com/thread.jspa?threadID=1037332&start=0&tstart=0 and after some more Diskwarrior-ing, headed to some of the library cache locations.... Here was his suggestion;
==================================
1. First run disk utility or some other good drive utility to make sure your HD is healthy
(permissions too).
2. Boot into safe made and clean your caches with a cache cleaner or manually drag
the following files to the trash:
com.apple.kernelcaches (a folder in /System/Library/Caches)
Extensions.kextcache (a file in /System/Library)
Extensions.mkext (a file in /System/Library/)
com.apple.ATS (a folder in /Library/Caches/)
com.apple.loginwindow.plist (a file in /Library/Preferences/)
Files that start with com.apple.LaunchServices (in /Library/Caches)
3. If the problem still persists, reinstall the latest 10.4.10 combo update (v 1.1)
in safe mode and repeat steps 1 and 2. )
===========================================
...so, many thnx KJK555... so far so good.
--- should others be having similiar problems with kernel panics or freezes (on 10.4.10) - check out the continuing discussion going on @ the above link (some have had success reverting back to 10.4.9). Its probably best to go through all the RAM checking / Disk Utility procedures (follow Dales' links) before heading to the library caches. ...and although this has currently has stopped my repeated crashes, it may not be a kernel crash fix for everyone.
Thnx for the reply again Dale, and good luck to all ----
Cheers,
J.

Unresolved Kernal Trap-Hardware or Software issue?!?!

I could really use some advice here. My PowerBook G4 is driving me crazy. For the past 8 months, it has these "fits" where I either get the Grey Screen of Death or the kernel panic messages all down the left side of the screen.
I've reloaded my OS three times and the issue seems to go away for a while, and then one day it goes off again.
Noticeable situations:
Computer is cold (it's in my office in the basement) after sitting all day... it's been asleep... I open the screen and boom... crash.
Airport is trying to reconnect with my local network after the computer has been sleeping for a while. (Where I've left the screen up but used the "sleep" command.)
Attempts to resolve:
After trying everything under the sun I know of, I thought there might be a RAM issue after reading some posts here in the discussion forum. I ran Apple Hardware Tester to find there was an issue with one of my RAM chips which upon further research suggested that it might not be seated all the way (hence the intermittent crash). So I opened up my PowerBook, switched the RAM chips around and that seemed to solve the issue (for a while). Oh, and the RAM passed all AHT tests afterward.
Question:
Is it possible that the heating/cooling cycle over the years has caused the RAM sockets to become "unstable"? Things seem to work pretty reliably when the computer is warmed up.
Here is the report from my last crash:

Good post.
Things to try;
1) disconnect all third part hardware and try the sleep function
2) reset the power manager
3) use terminal and type in reset-vram
reset-all
4) what I suspect, where did you buy the ram? remove any third party ram and just use what came with the powerbook
5) the hardware test is not going to tell you if the ram is not compatible, it can make mistakes and say its ok when if fact it is not. Although more or less if it does say its a problem then it is a problem but just don't rely on its final word.

Unresolved Kernel Trap - can't restart after reinstalling OS

hi, i just zeroed out one partition on my G5 after backing up the files to another partition. i wanted to reinstall a clean OS. i wasn't able to install from the CD in the G5 - kept getting a weird broken apple logo and the computer fan would start to rev. - so i reinstalled from the original discs but had to do so from my iMac G5 with the G5 connected as a FW drive. here the install went fine and i was even able to boot from the newly installed OS as well as the backuped up system from my iMac G5.
however the problem starts when i disconnect the G5 and reboot it. the OS starts to load, i see the apple logo but then a dark grey screen descends and i am told i must restart the computer. the text on the screen says "Unresolved Kernal Trap (cpu 0)" followed by more info that i don't understand.
i can't seem to boot. i checked the prermissions by hooking back up in FW mode to the iMac and apparently there were some issues which disc utility resolved. still i can't restart the G5.
the hardware configuration i have is identical to what i had when the unit arrived a year ago.
can anyone please offer me a solution?
thx

Hello I am having a very similar problem. I am running a G5 with two drives.I haven't used the drive the computer came with as I transferred the drive from an older g5 into the #2 slot and have been working from that.(OSX Tiger upgraded from Panther)
I purchased some new software so decided to do a clean install on the newer drive (Purchased with OSX Tiger installed.)
I cannot find my original install CD's which came with the machine(I know I'm an idiot) so I tried the install from my Tiger CD.Every time I tried to restart with the CD I got the unresolved Kernel disaster described above.Luckily I managed to boot up the computer on the old drive by resetting the PRAM as I started up.
I called the local Apple shop and he advised creating a disc image of the CD and from that navigating to System/installation/packages/OSinstall.mpkg and installing from there. I had a little trouble figuring out how to create a disc image from the CD so navigated to the above installer within the CD itself,opened the installer which then proceeded to successfully install the OS on the erased drive."I'm saved" I yell! BUT when I try to boot up the newly installed OS I get the same unresolved kernel thingo.
But wait there's more,now I can't boot up at all,not even using the PRAM trick.
Remember I don't have the Discs that came with the machine to boot up with.
Am I totally screwed?
Any help would be greatly appreciated
Cheers
Brandon

HELP!UNRESOLVED KERNEL TRAP!

there also have orther kinds of "unresolved kernel trap" will emerge sometimes when computer was start up
my ibook's profile are:
10g 128m
powerpc g3 500mhz
mac os x 10.0.9 are new installed and in use
have no partition in harddisc
before 10.0.9,mac os 9 was used in good status without above problems
if it can be resolve by upgrade to later version of mac os x system?
those really are pians in my ***!
help me please!
thanks a lot!

hello!
thanks for your reply!
the memory devices i used on my computer are all compatible with mac 9.0 or later (it was marked in manual).
the kernel trap emerge frequently while starting up and web site openning as well as device connecting.
apropos,i can never open Disk Utility since mac os x v10.0.4 was installed,every time i do it,the notice must be emerge like this:
the application disk utility has unexpectedly quit,the system and orther applications have not been affected.
what's up? the hard disc used to be successfully checked without any problem
in mac 9.1 system.
i'm trying to upgrate into mac os x v10.4,and hope they will be resolve.
thank you anyway!

Hello again --
The PB made a trip to Apple and apparently the stock Apple memory was defective. But, there's still a problem. I got the 'book back this week and assumed that since Apple had it and repaired it, all would be well.
Well, maybe not.
After getting it back, the same issue of the system slowing down and usually hanging with a spinning beach ball of death seems to be present.
So, assuming there had to be some sort of software problem, I did an erase/install after rewriting the partition tables, etc. as per Apple's troubleshooting recommendation. So... new system on board after the RAM repair. Then, I reloaded my software (from CDs) and then restored my music/pics/etc. I still ended up having to use the power button to escape a massive slow down/hang. The following apps were open at the time:
Mail, Safari, iTunes, Console, Activity Monitor, Entourage (I think). The way it happens is like this:
All seems well -- then, I mouse (trackpad or external mouse; happens either way) to either click a tab in Safari, or check mail... anything like that... and that particular program gets a spinning beach ball. But, the other apps are still up and going (for now). So, I click on another one to make it active. In a few seconds or so, it too gets a beach ball. And, on, and on. The last time this happened, the Console did manage to catch the following:
Sep 16 21:49:27 Chickenhawk KernelEventAgent[35]: tid 00000000 received unknown event (12)
Sep 16 21:49:46 Chickenhawk KernelEventAgent[35]: tid 00000000 received unknown event (12)
Sep 16 22:12:07 Chickenhawk /System/Library/Frameworks/ApplicationServices.framework/Frameworks/ATS.framewo rk/Support/ATSServer: FOExceptionMainHandler caught a fatal exception at 0x000476d8
So, I restarted, logged off and then set about doing the hardware test.
Last night I ran the hardware test in loop mode for 8 hours/15 cycles. Nothing untoward. Everything looks good. This morning, I reset the PRAM (like a bonehead, I forgot that earlier). In any case, I'm befuddled. With the exception of Entourage, everything else was Apple.
Any clues from the Console log?
Thanks again for your help; I truly appreciate it.

Unresolved kernel trap - help!

I was watching a DVD on my powerbook when a bunch of text filled the screen. Apparently I was experiencing an "unresolved kernel trap". I tried rebooting many times and got the "You need to restart your computer..." message shortly after the grey screen with the apple appears. Rebooting using "command s" resulted in the a repeat of the kernel attack text on my black screen. The disk works fine in target mode and I ran Tech Tool on it and found no problems. I was able to boot the computer in safe mode, so I repaired permissions but when I rebooted normally I had the kernel panic again immediately. What should I do next? Is there something I can do in safe mode?
It may be worth noting that this particular book is a real lemon and has had the logic board replaced twice. Could it be hardware? RAM?

Following instructions from Jeff* in a different post I zapped the pram and reset the open firmware. It's booted. Been up and running for 2 minutes. So far so good. Thanks Jeff*!

Kernal trap crash with sleep mode

Hi,
After installing the newest OSX my mac crashes randomly when being opened after having been on sleep mode for some time.
Here's the problem report - can someone please explain to me what the problem is and how to fix it, thanks!
I find it strange that it doesn't crash everytime... a kernal trap is a kernal trap, right (whatever a kernal trap might be, anyway)!?
Help is greatly appreciated!

OK, I'll try that. I'll disconnect the soundcard and try putting it to sleep and wakening it again.
It's getting late in Denmark and I have to get up early to go to work. My next post will be around the same time tomorrow.

I have also used Carbon Copy Cloner to transfer all of the old hard drive onto a different one (Not a newer one, just one that was being used for storage, that our older OS4 was on.) We still seem to be getting the same effect (although it is not near as sever) after having transfered the data. We completely wiped the old hdd an reconverted it into a storage drive, and it seems to be able to read & write data efficiently (although, I should note, the entire system seems to be slower than it was; it was slower even before we swapped drives, which leads me to think RAM?). Never the less before we swapped drives, we could hear the old drive randomly spin at very high speeds. (In turn, this caused the fan to also spin at a very high, and unusual, RPM.) We were experiencing, during this time, system failures and freezes (where nothing would respond, no Mouse or Keyboard interaction, eventually resulting with a system restart that would not always restart).
The information is completely backed up and we have performed a system reinstall (Not a fresh from scratch system re-instal, but a system reinstall none the less.)
I believe the hard drive/RAM may be failing, but am otherwise unsure. Does anyone have any idea what my problem may be???

Try booting from an external drive (firewire) if you can and see if the problems persist. That might isolate it being a particular drive issue.
I think on your model Mac the fans are controlled by software. If the system is crashing the computer automatically goes into fan overdrive to prevent overheating.
If you have multiple RAM chips try pulling all but the minimum required and see if the problems go away. Swap and test again until you have it isolated.
There's a utility called Memtest that's supposed to test RAM.
Apple Hardware Test not showing anything isn't proof nothing exists. Sometimes it helps to run an extended test.

It would be helpful to know which threads crashed, though the combination of issues suggests a hardware issue.

G4 MDD 1.25/10.4.10: Unresolved kernel trap(cpu 0): 0x300 - Data access

Need help understanding why this happenning ; now twice in 2 days.
Only change is that I added a UVC webcam ( runs native on 10.4.10) and I have been using Skype.)
Thank you...!

If you want someone who can understand that log, copy and paste it in a new post in the Tiger Forum. sometimes someone there will see it and respond; title it something like, "what does this panic log say please?"
Otherwise try the following:
You are experiencing a Kernel Panic as seen and described in Apple doc.#106227. If not, disregard.

Hi Hatter,
Thank you for the feedback, I am already in the process of doing those steps before I wrote this question. The reason I am posting this is because I would really like to see if others have experienced problems with this. I want to be prepared with information when I have my appointment with the genius bar (this is my production mac and I need to finish up a project before I can get some known issues fixed).
By knowing if others have seen issues with cpu 2 this will help me in understanding the problem and know if I'm getting the correct information from the genius bar. IE I don't want to be back at the bar with my HEAVY mac pro trying to troubleshoot this over a long period of time if someone here has seen a similar message and I can shortcut what might be a long and tedious process of fixing this.
AGAIN, thank you for the feedback but I am doing those steps.

What is an unresolved kernel trap

I am preparing the G4 iBook to give to a friend and have eresed the HD, installed Leopard and upgraded to 10.5.8. I am now installing software etc but it keeps having kernel panics and the Problem Comments note an "unresolved kernel trap."
The last KP occurred when I set about using Disk Utility to fix permissions in the hope that would solve the problem - that was before I had spotted the u k trap phrase in the report.
Until now the computer has worked for nearly 9 years without going wrong (worn out keyboard replaced with OEM about a year ago). Does anyone know what this is and how it might be located and fixed please?
Thank you.

How to resolve kernel panics?
Depending on the log information, the cause may be bad RAM,
or other hardware weakness or failure, incorrect software or an
incompatibility within the system. Sometimes fonts can do it...
On occasion, a failure of a component on the logic board does it.

{PS: did you secure-erase and reformat the hard disk drive before
installing a new system? This can help fix bad sectors on the HDD}
