Video related Kernel Panic

Question

Video related Kernel Panic

In the last week or so, my iMac G5 has been experiencing kernel panics when I wake it up in the morning.

It only seems to happen after several hours of sleep, and not if it's been asleep for just a couple of hours. Sometimes it will KP again on restart.

The KP is always accompanied by video distortion. Sometimes it happens immediately, and sometimes after a few seconds. This morning I was able to read a short e-mail message before it happened.

The Apple Hardware Test reports no hardware problems after both the basic and extended tests.

Yesterday, I did a full erase and reinstall of the OS. No luck. It happened again this morning.

I'd be very thankful for any suggestions as to what I should do at this point.

Here's the panic log, which seems to confirm that it's a video problem:

You state;

It only seems to happen after several hours of sleep, and not if it's been asleep for just a couple of hours.

I did a full erase and reinstall of the OS. No luck. It happened again this morning.

The panic log's highlights:

PC= 0x009F4BFC; MSR=0x00009030; DAR=0x46DB634E
XCP= 0x0000000C (0x300 - Data access)

com.apple.GeForce(4.0.6)@ 0x9d5000

The vedio card (VideoRAM) seems to cause the issue. Even if your iMac G5 does not address to this issues, I suggest to discuss with AppleCare service.

I am seeing this exact same kernel panic - only my does not occur related to sleep/wake. Mine occurs when attempting to zoom or resize the window in Preview.app. I am running an older G4/400 (AGP) with a GeForce video card.

I am filing a bug report as we speak.

Any resolution?

I also have this problem.

No resolution whatsoever - and Apple is ignoring my Bug Reports.

macvoodoochile and Matthew,

your ( macvoodoochile ) panic type and the computer configuration differ from the original poster.

My suggestion is based on the current given information from you.

First verify whether you had updated Firmware Update 4.2.8 for G4/400 MHz AGP.

1. You need to disconnect a GeForce video card from the AGP solt, and connect ATI's RAGE 128 PRO graphics card to the slot which came with your computer.

2. Start up the computer from Mac OS X 10.4 Retail disc which has been exclusively used by PowerMac G4/400 AGP. Run Disk Utility program and repair the Disk volume and Permissions. Post back if you detect any errors explaining about details.

3. Resetting PRAM when you restart the computer. Make sure to disconnect ALL third-party hardware-- Do not reconnect them until you finish troubleshooting.

4. Restart the computer into a Single-user mode. Perform "fsck -fy" for two times.

5. Restart and test the computer whether the Kernel Panic recurs.

6. If the Kernel panic recurs, try troubleshooting third-party software.

Fumiaki - pardon me for being dense - but it basically sounds like what you are saying is remove the 3rd Party video card I installed to overcome shortcomings of the lame video card that came pre-installed with this machine, reinsert the lame OEM video card and shut up. If that is indeed what you are saying I find it to be useless information. But thanks for offering your insight.

And just an fyi - yes I do have and have always had the firmware update (as would be seen in the bug report I filed with Apple). I have reset the PRAM and repaired the permissions several times. The video card in question has been working flawlessly in this machine for the last 3+ years since I first installed Mac OS X (actually the very first Mac OS X release had problems with it). The kernel panics only started occuring after the latest update to Mac OS X 10.4 Tiger and continue through all 10.4.x updates.

Yes, you need to remove the third-party video card, because of "panic(cpu 0 caller 0x00901A84): Apparent UniNorth Hang: AGP STATUS = 0x00000000."

In an earlier boot process, the ROM on logic board is about to check the video properties information and videoRAM as well. This RAM may be a problem.

Find someone who has an original card or another one that has the same specifications, and test it. I am sorry to hear that the original one is out of order.

I also have a 1965 VW out back that doesn't run. I am looking for someone who has an engine I can borrow to test it out.... sheeesh.... no offense intended, but your troubleshooting methodology is flawed if you ask me.

Pretty cut and dry here - it worked with all before Mac OS X Tiger. Now its broke AFTER Mac OS X Tiger.... hmmmm....... heck we even know the kernel extensions causing the problem.... hmmmm.....

You've got to explain me the reason that my troubleshooting methodology is "flaw."

10.4.3 does NOT resolve the Preview.app resize/kernel panic issue with a Power Mac G4/AGP & nVidia geForce4MX 64MB card.

I've set GraphicConverter as the default image viewer and Acrobat as the default for PDFs. Not as elegant, but...

I sent Apple a bug report.

I've been getting a kernel panic in Preview.app ever since I went to 10.4. I also have a GeForce 4MX 32MB. My panic comes any time I open more than one picture in Preview.app. Now that I have updated to 10.4.3, I also got one kernel panic waking up from sleep. Not a good sign.

since your videocard is not OEM, may I presume you have been to the video card manufacturers web site and checked for updated drivers for said card?

It would not be the first time old/outdated drivers have caused problems after an OS update.
