Starting late yesterday, my system catastrophically freezes shortly after I start moving things around in an AE comp. Additionally, Photoshop CS6 did the same thing to my system this morning when I was using the Marquee tool. I've been using CS6 Production Premium for the past 3 weeks or so, with almost zero problems in any of the apps until yesterday.
When it freezes, one screen goes black (the main one, powered by an Quadro 4000), and the other is totally stuck on whatever it was showing until I hold in the Power button and shut it down. I have a feeling it could have something to do with the Quadro card. I hope it doesn't, because I'm using the raytracing engine in AE.
I registered CS6 Production Premium midday yesterday. I wonder if this could be related, since AE ties in several third party pieces of softwarelike Mocha AE (which I opened) after registering CS6. I have not made any other software/hardware changes over the last few days.
Coming off a clean Lion install, everything has been incredibly fast and stable until now. I wondered if it could have to do with the disk cache because I was doing a ton of rotobrushing, 3D tracking and precomped raytracing leading up to this, but it's happened now in Photoshop too. (My disk cache is set up on my fibre RAID)
The crashing in AE is not specific to my project, even though it started on a CS6 project that's gotten very, very complex. I can open it create a new project, throw a solid in, and start messing around with it and within a minute it crashes the Mac.
Anybody seen anything like this? I'll try unplugging my Quadro next and see if it still happens.
Hardware:
Mac Pro 4,1 (2009)
Two Apple LED 24" displays
NVidia Quadro 4000 (First slot, 1st display)
NVidia GT120 (second slot, 2nd display, stock Apple card)
2 x Apple Xserve fibre RAID-5 (3.5TB each)
24GB RAM (6x4GB in slots 1-3 and 5-7 as recommended for MP 4,1)
Software:
Clean install of 10.7 Lion (I did this 3 weeks ago in prep for CS6), updated through 10.7.4
CS6 Production Premium (with x.0.1 updates)
I don't have the Mac up in front of me right now to list the NVidia and CUDA drivers, but I installed them fresh from the web three weeks ago, and I checked for updates yesterday.
CUDA driver is 4.2.7. GPU driver is 7.18.18 270.05.25f01
Also have a Blackmagic Intensity Pro installed with latest drivers, which I've disabled in AE.
Does anyone know how to read this? It's the crash report Apple generated when I start back up.

Never mind, everyone. I just had this crash happen to me outside of the Adobe apps. I booted into Snow Leopard 10.6.7 (on my other startup disk) and did some work in DVD Studio Pro. Eventually it gave me the same crash. So while the Adobe Apps definitely trigger the problem right away, it apparently isn't Adobe-specific.
Yes, two cards can be a disaster on the Macintosh, depending on many factors. We took all the extra cards out of our video production systems simply to eliminate all OS/hardware issues. Ww sufferred a bit of lag time in certain apps but that was easier to deal with than inexplicable crashes. Are you spending any time on the Apple hardware discussions at apple.com?
Sorry you're having trouble but I wanted to say thanks for offerieng up a good suggestion in your thread; hardly anyone does that around here and it's really helpful. Good luck with your search for a solution. If you find one, consider coming back and closing the thread.
Thanks, Pharther… what am I looking for exactly?
I think it might somehow be related to the Quadro card itself or to the logic board in the Mac. It happens even when either display is unplugged from the card, but hasn't happened yet when I've totally removed the card.
I've been using the Quadro card in combination with the GT120 for most of a year on Snow Leopard with zero problems. I fresh installed Lion a few weeks ago and made sure at the time that I had all the latest updates on the OS, apps, and drivers. It was rock solid on Lion as well for those first three weeks.
I'll head over to Apple discussions to continue any troubleshooting on this issue. Thanks everyone!
I have exactly the same problem (crash report looks very similar). Just bought a new Quadro 4000. Worked fine for two weeks. Then my Mac Pro 4,1 (2009) started to freeze at random moments. Even during start-up. Tried everything to solve the problem. (Resetting PRAM, hardware-test, repair permissions, re-install/update drivers, clean cashes etc). If I re-install my old (original) video-card, everything works fine. As soon as I install the Quadro 4000, my system starts freezing again.
Did jou find any solution for it?
I sent the Mac in and they found problems with the logic board and replaced it. But when I got the mac back and put my Quadro back in, I still had the issues. Now I've put the two stock GT120s back in and it's worked fine since. I sent the 4000 in under warranty and hopefully will get a repaired or replacement unit back soon so I can try again. I really need it for PP and AE.
The 4000 worked great for me on Snow Leopard for almost a year, and it worked great on Lion for about three weeks.
After removing every hidden piece of software (using file buddy) that had something to do with Nvidia, my system was still freezing with the quadro 4000 installed. I called Apple, and they did send me a new quadro 4000 right away. I installed it, and no more freezing after that. After a week of looking for a software solution it looks like is was the quadro 4000 hardware... I wonder for how long the new one will work...
