Display freezing - NVChannel(GL): Graphics channel exception

I'm having the most annoying problem. My display sometimes locks up without warning. Sometimes I get the following output in my system log file:

kernel[0]: NVChannel(GL): Graphics channel exception! status = 0xffff info32 = 0x8 = Fifo: Watchdog Timeout Error
kernel[0]: 0000000c
kernel[0]: 00000010 00005097 0000047c 00000000
kernel[0]: 00000486 00001528 00000000 00000003
kernel[0]: 00000000 00000000 00000000

I'm not running games or anything graphic intensive -- sometimes just mail and Safari. It's not reproducible; there isn't 1 single thing I can do to get it to happen. I've reset pram, the PMU...

Does anyone have thoughts on whether this is a driver problem or a hardware problem? Thanks

MacBook Pro 2.4 GHz Intel Core 2 Duo, Mac OS X (10.4.10)

The only solution: shut down the PC, connect the new display and then turn on again 🙂

my MBP Santa Rosa 15" freezes EVERY TIME when I connect an external display or peojector. then reset, then "it works"...

params:
- MBP 3.1 15" 2.2ghz
- bought november 2007

I filled out the form on http://www.apple.com/feedback/macbookpro.html maybe You all can do it without the hope of the "personal answer".
no comment.

I'm also getting this problem from WoW after it's been playing a while.. I too checked temp and everything seemed cool. I'm actually on 10.5.2 9C20 not 10.5.1 and even though it had a graphics update (which fixed some issues) this issue is not one of the fixes 😟

Around same time in my log though i noticed disk requests were also sent by system by spotlight to do something on one of drives..and both the GPU and SATA card reported timeout or not found. Seems to me like the problem could actually be related to task ordering and nvidia card being shorthanded pipe bandwidth by another device because the OS decided that while the card needed the bandwidth, spotlight should update the index on one of the SATA drives. I could be misreading though.

Hello,
I also see the same problem , the macbook pro is just 6 weeks old (built in 10/2007).
The rom version of the graphics card shows: 3175.
It happened to me twice today while working with adobe photoshop/bridge.
The system log logs this:

I will contact the dealer next week, this is not what I expected from my first mac.
I'm afraid it is an hardware issue. I'll keep you posted how Apple in Germany deals with that.

I had filed a bug through ADC to apple on issue to see what they would say and they said they already had an open ticket on issue. Bug ID# 5683909 and in email when i asked about status of original bug ticket then. They Replied:

"At this time, there isn't any new information available for this issue. I have checked with engineering, and the issue is still being investigated.

We will do our best to keep you informed as new information becomes available, or to contact you for additional testing/regression/debugging. Please be sure to regularly check the release notes for potential or related fixes that might affect this issue. "

Feb 6, 2008 10:42 AM in response to MysticalOS

Have you filed the bug about the NEW MacBookPro 2.2GHz (Santa Rose chipset) with the NVidia GeForce 8600M GT graphic card?? Or about an older MacBookPro with an ATI graphic card?

I also made a bug report about the NEW MacBookPro 2.2GHz (Santa Rose chipset) with the NVidia GeForce 8600M GT graphic card!! The bug ID is: 5727589

I'll write if there are some news.

Feb 9, 2008 10:46 PM in response to livio

Same problem here. I have a MBP 17" with the well known NVidia GeForce 8600M GT graphic card.
Nvidia does not support online the card for mac so no drivers found.

Apple do not recognize this as an issue so my MBP freezes like a Vista PC and I can't do nothing else that reboot and reboot. I have noticed that it freezes sometimes less when you've the AC plug on without the battery, but it's not a solution.

More than this I have issues with random Airport disconnections when I have the battery instead of the AC and with parameters for printing with Leopard on my Epson rx 500.

This time Apple did not do a good job, this issue is on from october 07, when I bought the computer and no solutions seem to arise...

Feb 10, 2008 4:15 AM in response to Teostress

I don't know what we need to do, that Apple finally fixes this bug!! I also have my MBP since October '07 and there is still no fix! The biggest problem is that we don't even know if the Apple developer team knows about this issue! Or if they think that we are only a few stupid clients which have no idea about what we talk...

We urgently need a fix for this VERY CRITICAL BUG!

Feb 14, 2008 2:41 AM in response to thomanjones

Err the Mac OS X 10.5.2 combo update and the Leopard graphic driver update afterwards fixed for me all problems!!!! So it was a software issue! I'm on a MacBook Pro 2.2GHz with Santa Rosa chipset (bought end-October 07).
iDVD and SecondLife work now without a crash and no "Graphics channel exception" occurs now anymore.

It's really strange that some people have this problem only now AFTER these two updates! What model do you have and when did you buy it?
