HELP!UNRESOLVED KERNEL TRAP!

hello everybody!
everytime while i connect a memory stick into my ibook through usb port,the white words with black background will emerge like these:
unresolved kernel trap(cpu 0):0x300 data access DSISR=0x40000000 DAR=0x077d6518 PC=0x077c1980 MSR=0x00009030

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!

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.

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*!

Unresolved Kernel Trap: Booting & System Errors.

The computer has been Crashing more and more frequently as of late.
The latest report gave me this:
2-11-2010:

We have ran a hardware check and it returned negative regarding any hardware defects.
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.
[X-Lab: The Apple Hardware Test|http://www.thexlab.com/faqs/aht.html]
[Apple's AHT support|http://www.info.apple.com/support/aht.html]
It would be helpful to know which threads crashed, though the combination of issues suggests a hardware issue.

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.
FJ has some good KP tips.

Panic(cpu 2 caller 0x001A4A55): Unresolved kernel trap (CPU 2, Type 14=page

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.
• About the cause of kernel panics:

The above link goes into a higher level in some ways than the others.
Good luck & happy computing!
{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}

Unresolved kernel trap 0x600 - now can't start computer!

Our Mac G4 (10.2.8, dual 1GHz, 1GB RAM) has been suffering from more and more frequent kernel panics and crashes (see my previous post: http://tinyurl.com/hxut9), and now seems to have died completely. This morning (it is left on all night, as it runs a kind of server) the screen was blank but the light was on, indicating it was running. No joy waking it up, so I held down the power button until it restarted. It then gave me the following message:
"Unresolved kernel trap (cpu 0): 0x600 - Alignment DAR = 0428005e2 PC=0x0008d3d8"
repeated all the way down the screen.
It now won't start up: it hangs on a screen with a blue background and white box with the progress bar stuck on "Waiting for network port mapper". All external hardware except screen and mouse are unplugged - usually, there's an external hard-drive and a scanner plugged in.
Can anyone help?
Some background: as I said in my previous post, we've had odd network issues with it recently, where it could access the internet, but the outside world couldn't access it (for the server, or for scheduled backups across the network). This was the case with the firewall on or off. An extended hardware test eventually (34th loop) gave the error code "modm /2 /8", which would suggest to me there was a problem with the MODEM, but we don't use that - only the network card. Disk Utility gave no errors.
Any help / advice would be much appreciated! Although we have a network backup of the data, we can't access it without that computer, and I need it urgently!
Thanks very much,
Alex
PS. Update: on the 4th go, it has now managed to restart! I am not optimistic about this lasting though, so would really like to resolve the issues...

Hi,
Really tough to tell from that little of info, is there more?
Does it boot at all? How often does it KP?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), does it KP then?
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Might try disabling some CPUs.
The cpus boot argument can range from 1 up to the total number of processor cores on your system.
http://developer.apple.com/mac/library/qa/qa2001/qa1141.html
You might try this also, thanks to old comm guy...
This can be done in open firmware,(boot with cmd+option+O+F held down).
setenv boot-args cpus=1
reset-all

Photoshop causing unresolved kernel trap

Has anyone else been experiencing full-system unresolved kernel trap crashes since the last Photoshop CS4 update? If I never open Photoshop, the system is fine - no crashing whatsoever. However if I even so much as open Photoshop, within a number of hours, the entire system crashes with the unresolved kernel trap error. It appears to have something to do with the video card as well.
One of my friends is experiencing this same issue on her PC with Photoshop. It clearly has something to do with with Adobe's last update since we both noted this new behavior right after their last update. Just curious how many others are experiencing the same thing and if anyone has any information about it.

hi sboben --
Just checking here . . .
Did both you guys repair permissions after loading on the Adobe?
If not, you might want to do that just to test the basic . . .

It looks like what I understand to be a kernel conflict or something. Something to do with multiple applications causing an unresolved task. I have also read that it might be due to loose RAM. Are there any suggestions?

Here's more if you need it;
You may be experiencing a Kernel Panic as seen and described in Apple doc.#106227. If not, disregard.

Unresolved kernel trap(cpu 0): 0x300

I had been having a number of kernel panics that did not result in a panic log. I did an archive re-install and this seemed to sort the matter. However, I have just had another kernel panic and this time there is a log - can anyone tell me what it might mean? I have no peripherals and the machine is as it came from the factory. Here is the log:
