  • 375. Re: Display freezing - NVChannel(GL): Graphics channel exception
    aberrant Level 1 Level 1 (10 points)
    After a full day of (heavy, graphics-intensive) work, I haven't been able to reproduce the problem:

    $ grep -i nvchannel /var/log/system.log | wc -l
    0
    $

    Hopefully we're all good here....
  • 376. 10.5.5 does not help with this problem for me.

    I can confirm that 10.5.5 does NOT fix the "NVChannel(GL): Graphics channel timeout!" or exception problem. To test this I scrolled through iTunes 8 albums via coverflow and sure enough as always after about 1 min my computer froze up. I then check console log and sure enough there is the dreaded "NVChannel(GL): Graphics channel timeout!" error. I will have to take back my brand new Macbook Pro back for a replacement of the logic board to see if that will fix this. I have a strong feeling that this is caused by the well known fact of the defective Nvidia graphics cards in all current Macbook Pros.

    i can confirm that something changed but nothing about the "NVChannel(GL): Graphics channel exception!" is fixed.
    i run front row this night for a second time...when i wake up this morning i take my remote and i could not change the track or the loudness. i stand up and activate my display. the whole screen was full of artifacts and other destructions. the system worked but i had to do a restart.
    it is very sad although some people post that apple respond on their bug reports with "this bug will be fixed in 10.5.5" and nothing is changed.
    next night i will replicate it one more time an the next day i will take a video and send it to youtube, fscklog and other macsites. i cant use front row and want my money for my mbp back.

    here my log:

    I'm having this problem too. But it's new, started only 2 days ago. I've updated to 10.5.5 and it still happens.

    Pardon the redundancy, but just to be thorough...

    Problem description: screen freezes, except for the mouse pointer. (Though sometimes the mouse pointer freezes too, but later.) The freeze lasts ~1-2 minutes, then suddenly is all is as normal. No particular user action seems to prompt this. Sometimes (and only under 10.5.4 so far), when the freeze ends, the screen redraws incorrectly: parts of windows that should be hidden end up being displayed on top of windows that should be in front of them.

    System: Mac Pro 2x2.66 Dual Core Xeon, 1 GB RAM, OS 10.5.5, all updates installed. Problem occurs for all user accounts on the computer.

    Video card:
    Chipset Model: NVIDIA GeForce 7300 GT
    Type: Display
    Bus: PCIe
    Slot: Slot-1
    PCIe Lane Width: x16
    VRAM (Total): 256 MB
    Vendor: NVIDIA (0x10de)
    Device ID: 0x0393
    Revision ID: 0x00a1
    ROM Revision: 3011

    Incidentally, we bought two computers of the same configuration at the same time, keep both of them updated, etc., and yet only one of the two is having this problem.

    I'm now almost 24 hours free of the nvidia bug, no error messages in the log, no freezes, no problems. Thanx Apple, I can finally start enjoying Leopard again. This took months and I serious considered going back to Tiger.

    Have been running 10.5.5 for 50h and it is still up, but have not pushed my MBP that hard, I have some work I need get done before i crash again. I have had on nVidia warning but the computer survived.

    kernel[0]: NVChannel(GL): Graphics channel timeout!

    By reading other threads out in the forums it still look like people are still having the same problem. It kinda make sense if the problem is the hardware. You really have to create good drivers to compensate for that....

    IS there any OS X OpenGL benchmark or burn-in testprog. we can use to trigger problem? I tried flipping through cover flow in iTunes but it didn't do the trick for me. Tonight I'll test it by keeping front row running all night.

    I'm also getting this NVChannel error. Macbook Pro 17 2.4 with 8600M GT.

    I'd like to add another instance for the record of this problem, which happened to a customer of mine. She started seeing the freezes on her Mac Pro around Sept. 5th. She had a stock GeForce 7300, and was getting the graphics channel timeout errors in the log.

    Screen updates would freeze; several seconds later, audio output would pause and the mouse pointer would freeze. This would last anywhere from 30 seconds to 2-3 minutes, and then everything would resume (including audio, which would pick up where it left off in the song). Disk- and CPU-using processes that did not involve audio or video would continue while the system was unresponsive. VNC continued sending data during the lockups, but didn't show screen activity either.

    System: Mac Pro, 2x Dual Core Xeon 3.0, 5 GB RAM (1 GB Apple, 4 GB OWC), OS 10.5.4.

    It got rapidly worse over the course of 2-3 days, to the point that the system was locked 20-30% of the time (locking for a minute or two every 2-5 minutes).

    My customer, the owner of this system, talked to me about it. We discovered the errors in the log, found this thread, and diagnosed the problem as likely being the video card.

    She called Apple the next day (Sept. 8), and was told that the video card was not likely to solve the problem. They advised her to look at RAM, and to reinstall the OS.

    Just to be sure, we went ahead and used a spare hard drive, did a fresh install of Leopard, and tried with each pair of RAM modules on their own. No change.

    This Mac is a critical system for my customer's business use, and she decided that rather than dealing with Apple Support a second time, she would order a video card with overnight shipping (a Radeon HD 2600 XT, about $130). We installed it the next day (Sept. 9, ten days ago) and there have been no freezes since.

    As I've reported here previously, a reliable way to elicit this problem is choosing the "thumbnail" view in QuickLook when more than a few items are selected. The system will freeze up and the typical "NVChannel(GL): Graphics channel exception" will be recorded in the console.

    Sadly, 10.5.5 did not solve the problem on my system. However, my MBP seems to be a revision behind your, so there might be differences.

    I have this problem also. It started a few weeks ago. I tried to edit some photos in iPhoto, and my screen just locked and got fuzzy picture and then white noise on the screen, no response for mouse, or trackpad... so reboot.

    After a couple of same situation (10 or more) I checked the logs and I found this problem: Sep 21 20:26:21 Dragon kernel[0]: NVChannel(GL): Graphics channel exception!

    After using google I found this page, (first hit.. it means something...)

    I was happy to see the new nvidia drivers in 10.5.5, but today I had the same freezing again...

    I have a Macbook Pro, 2.2 GHz, Nvidia 8600 gt 128Mb..

    Well, if this is a hardware problem of the NVIDIA chip, then Apple should use the NVIDIA's $90 million protection money to start recall these machines (and cards) and fix them.. since they say this is a Mac and not a f** PC which just does not work.

    I hope the best...

    I was blissfully ignorant of this problem until I upgraded to 10.5.5. Within one hour, I experienced the NVChannel error. Since then, it has recurred about a dozen times. I had no trouble with 10.5.4 or any other prior versions. So far I have not experienced any odd graphics behavior in Win XP SP2 under Boot Camp.

    I have a mid-2007 Santa Rosa MBP 2.2 GHz. 8600M GT ROM is 3175.

    We are at 10.5.5 and the nvchannel exception is still here. With earlier releases I thought it was a software, driver-related problem, but I am no longer sure about that.

    Till some months ago I had this issue only when using Aperture. I stopped using it and everything was fine.

    Now I am able to reproduce the error by quicklooking at multiple image files: if I select "a lot" of jpg or nef files my machine freezes and I find the nvchannel-blah in the logs. It is quite easy to reproduce with NEF (raw) files.

    Anyway, I downloaded the demo of a 3d game (maybe quake, I do not remember) and played with it for half an hour - several times - without experiencing any problem.

    Can you try and reproduce the problem by quicklooking at multiple image files?
    1. select the files
    2. quicklook
    3. press cmd+enter or the "index sheet" icon.
    4. select an image and go back to "index"

    Repeat several times the steps 3 and 4, or change folder. I am able to get my machine frozen with 1 to 10 attempts. I am good, aren't I?

    Yes! I can reproduce the problem using your test. The first few times it did not work but then I used quicklook on 65 images. As soon as I clicked thumbnail view the problem started.

    It's interesting to note that the display does slowly change and the thumbnails eventually started to fill in. It's just very sluggish and the NVChannel errors periodically appear in the syslog. I was logged into the system remotely via ssh and noted that Terminal.app began using 99% CPU. That's noteworthy because I had clicked on an open Terminal window as soon as the sluggishness began.

    Also interesting is that sometimes the problem is not fixed by rebooting the system. I have tried to boot but still had the graphic corruption appear. Sometimes it appears immediately and sometimes it appears later in the boot process before the login window appears. This time around the system booted up without issue.

    It is simply not plausible (at least in my case) that this is anything other than a hardware issue. Here's why:

    I own two Mac Pros (2x2.66 dual-core Xeon) which I bought at the same time. Both running the current OS, fully patched. One of them had the problem described in this thread, the other did not. So (1) I booted the problem machine in Firewire Target Disk mode, connected it to the good machine, booted the good machine from the bad machine's hard drive, and did NOT experience the graphics problem. Therefore, the problem is not caused by anything on the bad machine's hard drive. Then (2) I booted the good computer in Firewire Target Disk mode, and booted the bad computer from the good computer's hard drive. With that setup, I DID experience the graphics problem. Therefore, the problem is not solved/avoided by anything on the good machine's hard drive. So it's got to be hardware.
