NVDA(OpenGL): Channel exception!

CPngN

Thanks for your help.

Richard

The advice of Apple Care was to revert the system back to 10.6.4 (in my case the MBP was delivered with that versoin).

With Snow Leopard the re-installation preserves user data and application by default. Just insert the DVD and start the installation (took about 1 hour).

For now my MBP is stable...

With 10.6.5 and 10.6.6 I had the effect when an external monitor was attached my system was stable, but without it I got the NVDA Channel Exceptions and my system freezed.

HTH, Ralf.

Hmmm, just re-installing 10.6.4 did not help. My MBP crashed again after one day. The screen did not show a color it just got unresponsible and the only thing I could do was to move the mouse pointer accross the screen.

Now I also resetted the SMC (see http://support.apple.com/kb/HT1379) as suggested by Apple Care. As the SMC is responsible for "Selecting an external (instead of internal) video source for some iMac displays" and I always have a stable system when an external monitor is attached, I hope this will fix it.

Did you try to reset the SMC?

Reinstalling 10.6.4 did not help.

I got a workaround at least for systems with two graphic chips:
don't use the NVIDIA chip. Download gfxCardStatus from http://codykrieger.com/gfxCardStatus and choose "Intel only" in its menu. That way the NVIDIA chip/driver is not used and the system won't freeze.

I now have upgraded my MBP to 10.6.6 and it's stable. See http://blog.bensmann.com/41633002 for my story and workaround.

HTH, Ralf.

This just happened to me.

My screens started some sort of crazy flickering, computer froze, I panicked and rebooted. Came back to normal, for now. Logs:

This just happened to me, again?! My computer froze. I had to reboot. 10.6.6 has been causing a lot of problems for me... Does Apple even read this stuff or is it like typing into /dev/null?

It has been said a few times in this thread, but please:

Leave feedback on this issue and KEEP LEAVING feedback. It is an avoidable driver related problem. Apple are the only ones that can deliver hassle free graphics driver updates.

Thanks. Done.

Getting the same thing.
Boo.

Just wanted to add my fury to this problem!!

I'm now having this problem. First it was my Airport and now this. I'm very unhappy with my new MBP thus far.

**** i'm so glad to find this thread.... this issue exceeds "real" macs, I have the same issue with an 8800 GTX, my log files reflect the same errors as the rest of you:

Mar 12 20:24:36 macpro kernel[0]: NVDA(OpenGL): Channel timeout!

Screen flickered about 3-4 times, and then hard lockup, I had a 16 day uptime prior to this, I only get this crash while World of Warcraft is running, have not had issues with Photoshop CS5, sometimes this error happens after 2 days, other times mostly 4-5, but I wasn't expecting it this time round... honestly thought there was some 'other' compatibility issues, obviously not as REAL macs are experiencing same driver issues, so where do we go from here men? I can test whatever kernel extensions from whatever version, seems like the extensions from 10.6.3 are good? Or do those also experience this glitch?

I believe this is a hardware problem. I also was suffering from the same channel exception errors (and screen corruption/freezes) and, on a whim I applied to the NVIDIA Settlement repair program. I sent my laptop in, they repaired the GPU and some other odds and ends (though they didn't specify what else they changed) and sent it back. Since its return, no channel errors and no screen corruption. I strongly suggest looking here to see if you qualify for the free repair:

Nah i'm pretty sure its not hardware error, this exact(?) issue happened on Vista with the graphics kernel mode driver, look on google for nvlddmkm.sys - nothing but problems
Same screen flicker, and those also result in a hard lockup, I had the problem myself with 170x series of nvidia Windows drivers, but 180 I remember cured me, problem did not occur for me with 7.

Anyway, I'm guessing it's the same root cause.... this is bs, how can they make the same sort of mistake on two independent platforms, and then not even have the balls to come out and admit how badly they screw up.

I ran the nvidia package for 10.6.4, (extracted packages and installed, replaced OpenGL Framework to compatible version) - Those were 19.5.8f03, I was able to reproduce the result, buttttt instead of the machine locking up, it recovered (first time ever)... I still had to restart because after I saw the same thing happen (same messages in kernel log) I could no longer use 3d apps, WoW just refused to work...

Now trying the vanilla unmodified 10.6.3 kexts, these are 19.5.1f01
