    hi,

    im working on an Mac Pro with OS 10.5.7 and these components:
    Dual-Core Intel Xeon 2 x 2.66 GHz, 8 GB RAM, NVIDIA GeForce 7300 GT)

    since the mac software update 10 days ago I'm getting crasy!!!
    every time I use "autodesk maya" the hole system freezes and dies off.

    within a ssh-client I'm getting the following informations:

    I found that Wacom ( www.wacom.com ) updated the driver for my Pen Tablet (Bamboo Fun) on April 9, 2009. I just installed it and will watch to see if it makes any difference.
  • LouisHH Level 1 Level 1 (0 points)
    Exactly the same with me after update to 10.5.7.

    iMac6,1 Intel Core 2 Duo 2.16GHz 4MB/2,5GB DDR2 SDRAM667MHz and NVIDIA GeForce 7300 GT.

    Freeze or pixelated screens happen several times a day, sometimes when browsing the finder or watching films on Safari websites. Don't have game software or Photoshop, and I have already lost data.
  • bobcole Level 1 Level 1 (5 points)
    Even after updating the Wacom software the computer froze after a period of inactivity with the usual ...NVDA(OpenGL): Channel exception!... error in the Console log. Now I'm looking for something else to try.

    Right before the computer froze, the Console log shows a count mismatch between the Address Book's database and the metadata (see ~/Library/Application Support/Address Book/Metadata). So, after making backup copies, I deleted the extraneous metadata records that were listed in the console log. Now when the Address Book is opened there are no exceptions.

    I'll see if that makes a difference.
  • bobcole Level 1 Level 1 (5 points)
    The fix to the Address Book problem did not prevent the computer from freezing up again. Had to power off and start up again.
    I just used the Disk Utility to fix permissions and, to my surprise, found that there was a big bunch of items that had to be fixed.
    Maybe that will help.

    The update to 10.5.7 seemed to have made it better first, but it turns out, that it got worse again as the computer now starts to crash again. Sadly the update information said it will do something good to the graphics but seems to have done the opposite.

    If Apple is aware of the problem, I wonder why they now have even more Computers with Nvidia. The forums everywhere get full of these problem reports.

    Nobody from Apple reading here? Are they already happy not getting kernel panic reports any longer?
  • DaveDowling Level 1 Level 1 (15 points)
    THis appears to be a common problem. I am having the same errors in my syslog - ie
    May 31 07:18:55 iMac kernel[0]: NVDA(OpenGL): Channel exception! status = 0xffff info32 = 0x3 = Fifo: Unknown Method Error
    May 31 07:18:55 iMac kernel[0]: 0000000b
    May 31 07:18:55 iMac kernel[0]: NVDA(OpenGL): Channel exception! status = 0xffff info32 = 0x3 = Fifo: Unknown Method Error

    My system is freezing frequently, and practically unusable.
    Does anyone know if this a software or hardware issue?
    Does Apple need to replace the video card under warranty ?

  • bobcole Level 1 Level 1 (5 points)
    Fixing the permissions with Disk Utility seemed to lengthen the time between freezes. But a freeze occurred nonetheless. In the error message, the "NVDA" seems to indicate a hardware problem. But the "OpenGL" and "Parse Error" seem to indicate a software problem. Anyone have any ideas?

    The following article points to hardware problems with other NVIDIA chipsets ( http://www.appleinsider.com/articles/09/05/30/appleextends_old_macbook_pro_graphics_warranty_to_threeyears.html ).
  • iotek Level 1 Level 1 (0 points)
    Yes i'm here to join the club!!

    Ive been having this same channel exception message for the last few days mainly when using graphic intensive software (maya, photoshop). Ran hardware tests-no errors, ran Memtest over night-no errors, done a completely fresh install of 10.5.7 - still crashing.
    Yesterday i installed 10.5 again, this time only updating to 10.5.5. Spent a good five hours work the system hard last night- No crashes-No problems.

    Sorry i cant be of to much help, but system rollback is working for me so far.
  • iotek Level 1 Level 1 (0 points)
    I would say this has to be an issue with the 10.5.7 update and it seems that a lot of people (including me) have the Nvidia 7300 GT card too........
  • Fred Nix Level 1 Level 1 (15 points)
    I agree...I suspect this is a 10.5.7 specific problem as well...
  • Luzyfer Level 1 Level 1 (0 points)
    I#m frustrated!!! I need my mac pro at work. he has to run without problems like totaly freezing and chrashing. I'm sure that the problem begans with the updating to version 10.5.7.
    now I will make a "Reverting to a previous Mac OS X version"

    http://docs.info.apple.com/article.html?path=Mac/10.5/en/15216.html


    I hope that will fix the massive problem!!!
  • amacbishop Level 1 Level 1 (0 points)
    Same problem here - since 10.5.7 was installed, I have reduced my machine to the bare minimum, using as few graphic-intensive processes as possible - switched off Spaces, stopped Dock animation, plain colour background - it's always when these things are happening that the Channel Exception occurs. Bit of a problem really as a graphic designer to have to avoid graphic-intensive processes ...

    Really need to get to the bottom of this - if Apple can sort the problem or NVIDIA can release a driver update - whatever will fix it!

    Has anyone managed to go back a version or two of Leopard to sort the problem? If so, which version? Thinking an Archive and Install from original Leopard disc may be required ...
  • Luzyfer Level 1 Level 1 (0 points)
    I daily worked with maya till to my leopard-update 10.5.7. at these day the system freeze everytime I use maya. so I can identify the exact point of time as the problems begans.

    I would say that the openGL features of my geforce 7300GT causes the system problems.
    apple and nvidia provide actually not helpfully massages or fixings
