NVDA(OpenGL): Channel exception!

Hi stefanschuler.215,

I have all the software and firmware updated. My model is Hi-Res glossy.

If it's just a hardware problem, so I'm lost, but I hope you can resolve it.

I'll wait for your news.

Hi Jorge,

I recommend you to go again to the Apple Store and show this thread to them.

I think it is a barefacedness that the won´t repair your notebook.

This cannot be happening on a machine that costs over 2000 $.

Maybe you should go to some different stores to explain the problem.

Maybe you´ll find one store that will do the repair for free.

Good luck!

Thank you Stefan. I'll wait and consider what you've told me.

Hi people,

here are two additional screenshots. Can anyone confirm this garbage on the screen, caused by the problem, too?

Hi, got a new logic board yesterday. The channel exception failure is gone, but now the new logic board causes another graphics failure. When ever i start with something on the mini display port connected, i got green rhombs over the whole screen. Now logic board number 3 is on the way. 3th replacement is scheduled for next week. In my opinion, the whole 2010er 15" series has a construction failure, that causes this graphics issues. I´ll keep you posted.

Hi, after the 3th logicboard replacement it now seems to work well. AppleSupport mentioned that there are a lot of faulty logic boards in circulation.

are you still under warranty when your having the problems and getting the logic board replaced? I am having that problem show up with the disk utility scan and the videos just love to stutter on the easiest videos, not even hd videos, the computer just doesnt seem as fast as it should be at times

Apple has extended the warranty for some macs with known display/video issues. They have a special video test, but in the most cases the test does not show any issues and so they will not exchange the logic board. What mac do you have? When disk utility shows up problems, you should first do a clean install of the OS.

I have the 2010 MacBook pro with the 2.53 ghz core i5, it's the 15 inch model

Yeah,

That happened to me if I had automatic graphic switching on when you rebooted, 10 secs at the login in screen and the machine would crash and burn. If auto graphice switching was off, all ok, no hangs or crashes. Like you I didnt have this issue before lion.

Im on a macbook pro mid 2010 i7

@Jim Tsigros,

I found a solution and it is working fine with me on my mid 2010 i5, I deleted the Apple Power managent KEXT inside the extensions folder, and now I have auto switching enabled, and no more halt at the login screen or what so ever.. everything is working fine...

You can simply copy the original file as a backup incase anything happened, so you can put it back, but actually I had no problems at all. Waiting your feedback..

Champion !

That did the trick !! My machine dosnt kernal panic at bootup if automatic graphic switching is enabled.

I have also check using gfxcardstatus to switch between the two cards to verify and still no problems.

Everytime I kernal panic'd I got those:

11/02/12 3:23:31.000 PM kernel: NVDA(OpenGL): Channel exception! exception type = 0x6 = Fifo: Parse Error

11/02/12 3:23:31.000 PM kernel: 00000069

11/02/12 3:23:31.000 PM kernel: 00000069

11/02/12 3:23:31.000 PM kernel: 00000069

11/02/12 3:23:31.000 PM kernel: IOVendorGLContext::ReportGPURestart

... then kernal panic and reboot !

Now they dont show up.

So I think at least in my case it may have been software related.

This was driving me nuts !

Thanks for the advice.

Hi,

I tried with the recomendation of Adel Sabry (Feb 11, 2012 8:25 AM), but in a different way and, at the moment, it appears that I have no more crash related with NVDA(OpenGL) messages.

What I did was the following.

1. I have extracted the AppleGraphicsPowerManagement.kext* from OS X Mountain Lion (10.8 Preview). If we compare the version of it with such at Mac OS X 10.7.3, are differents (at least in my system).

Mac OS X Lion 10.7.3: 100.12.42

OS X Mountain Lion 10.8 (Preview): 100.12.53

I have seen differences too, between my equipment (MacBook Pro Mid. 2010) and one MacBook Air Mid. 2011 (comparing Mac OS X Lion 10.7.2 in both), with different versions in this files and another related with power.

2. I deleted original AppleGraphicsPowerManagement.kext from /Sytem/Library/Extensions/

3. I installed the version 100.12.53 using Kext Wizard (http://www.osx86.net/view/2057-kext_wizard.html). There is another option from Groths.org (http://www.groths.org/?p=571).

4. Restarted.

With this option, anyway, I cannot see now AppleGraphicsPowerManagement.kext in the list of extensions at System Information. May be another way not to delete it before...

I don't know if it is the best way, a correct way or a permanent solution. I just put it in the forum.

Best.

* /Sytem/Library/Extensions/

PS: Intead the installation, the "solution" may be the deletion of the original file... I don't know.

I left the 100.12.53 version here: http://i.min.us/iyWnzid1dEljr.zip

Ah... May be necessary to Repair Disk Permissions after install Kext (just in case).

@Jorge Castillo S.: Any success so far not having kernel panics by replacing the kext file?

Hi everyone, till yesterday I'm reading through all these posts and articles affecting the MBP Mid-2010. And sadly I'm also affected. I already installed gfxCardStatus to monitor the used gfxCard. In my case I cannot exactly blame the swichting process, having some kernel panicks in inconspicuous situations. For example yesterday I just enlightened my MB after turning the screen off while it downloaded a file. Without explicitely selecting the open finder window I tried to move a file in there and bam, the almost each and every day seen black screen appears.

I installed the MBP video update from here for Lion http://support.apple.com/kb/TS4088, hoping it prevents some crashes. In respect of the warranty I'm not sure whether my MBP would fail that mentioned test and I would have the extended warranty. On the other side, having read many posts from you, replacing the logic board seems to fix the issue in some cases. But honestly I'm not sure whether I got the nerves to first having to discuss my warranty extension with apple and afterwards having my logic board exchanged twice. Like you all I'm really disappointed in Apple and their missing participation in this discussion about that issue!

my crashes:

- kernel panicks during startup

- kernel panicks during usage of MBP

- endless white-screen on shutdown
