Q: NVDA(OpenGL): Channel exception!

I have the error above on the intel iMac 24" when running Second Life.

Error lines from syslog can be:

avalon-3 kernel[0]: NVDA(OpenGL): Channel exception! status = 0xffff info32 = 0x3 = Fifo: Unknown Method Error
avalon-3 kernel[0]: 0000000b

and

avalon-3 kernel[0]: NVDA(OpenGL): Channel exception! status = 0xffff info32 = 0x6 = Fifo: Parse Error
Feb 23 01:53:22 avalon-3 kernel[0]: 0000000b

If this happens SL is going to freeze up and die

Hardware failure?
OSX bug?
Application bug?

iMac 24" Intel Core 2 Duo 2.16 GHz, Mac OS X (10.5.6), NVIDIA GeForce 7300 GT

    I think you get the disk errors because the computer locked up while doing things. You can pretty much expect that on any operating system if you just pull the power without shutting down, and that's effectively what these crashes are to the OS. The OpenGL errors though are a result of either the nVidia hardware crashing, overheating, or the drivers need a bugfix.

    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.

    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:

    http://www.apple.com/feedback/macosx.html

    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.

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

    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:
