    Sorry to hear that. It's been five days for me now and I haven't had a single KP. But it could be just luck.

     

    Good news is that I've received an e-mail from Bug Reporter confirming that my bug report is a "duplicate", i.e. that this is a known issue:

     

    Kernel panics with OS X 18.2: A known issue

  • kevloucat Level 1 (0 points)

    No problem. I REALLY appreciate you posting the hack via the blog. It was worth a try. It's funny that I'm not really that upset about the KP other than annoyed. Going to keep trouble shooting...

    kevinloucat-

     

    You kernel panics are all occuring as a result of the same routine, the GeForce driver.

     

    But there are three different kernel panics in the four reports:

     

     

    panic(cpu 2 caller 0xffffff800f2b7b95): Kernel trap at 0xffffff7f90a27975, type 13=general protection

     

    panic(cpu 6 caller 0xffffff801c0b7b95): Kernel trap at 0xffffff7f9d7d0975, type 13=general protection

     

    panic(cpu 2 caller 0xffffff800d2b7b95): Kernel trap at 0x0000000000000000, type 14=page fault

     

    panic(cpu 2 caller 0xffffff8009051c07): "IOGMD: not wired for the IODMACommand"@/SourceCache/xnu/xnu-2050.18.24/iokit/Kernel/IOMemoryDescriptor.c pp:1424

    I'm also getting this panic (3rd time in 6 days) and I have 3 NVIDIA GeForce GT 120 cards with 3 LED Cinema Diplays on a 2009 MacPro

     

    Sat Sep 29 10:31:45 2012

    panic(cpu 6 caller 0xffffff8016851c07): "IOGMD: not wired for the IODMACommand"@/SourceCache/xnu/xnu-2050.18.24/iokit/Kernel/IOMemoryDescriptor.c pp:1424

     

    I'm going to revert to the older IOGraphicsFamily like Betalogue (link below) since the driver upgrade coincides with my first crash on Sep 24 2012.

     

    Solution (hack) for kernel panics in 10.8.2?

  • kevloucat Level 1 (0 points)

    Well I removed one of my GeForce 120 cards (the one my secondary monitor was hooked up to) and the kernel panics have stopped. I've now worked a week without a kernel panic.

     

    I guess I'll look to replace it, since I'm not sure if Apple's going to address the issue.

  • Pierre Igot Level 1 (15 points)

    Far be it from me to tell you what to do, but replacing a video card because of a software bug strikes me as a bit extreme, not to mention potentially ineffective. I think it's quite clear that these KPs are caused not by a defect in our GT 120 cards, but the very presence of more than one GT 120 cards in our machines. There is a bug in the updated graphics driver included in 10.8.2 that triggers this problem.

     

    The fact that you don't get KPs when you remove one of your cards does not prove that the card is defective. In fact, I'd be willing to bet that if you removed the OTHER card, the KPs would cease as well. Now, you MIGHT avoid the KPs by replacing one of the GT 120 cards with a different model/brand of card, but there's no guarantee.

     

    I still hope that Apple/NVIDIA is sufficiently aware of this issue and takes it sufficiently seriously that it'll be addressed soon in a software update soon.

  • kevloucat Level 1 (0 points)

    Point taken. I actually had a moron moment and realized I had the mini-display port as well as the DVI. Just picked up and adapter and I've got two monitors again. Only half the video ram, but this is a great solution until Apple creates a fix.

  • Pierre Igot Level 1 (15 points)

    Yes, that's what I would have done myself (mini-display) if my hack hadn't worked. But it has worked and is still working so far for me, so I'll leave it at that for now. When 10.8.3 comes out, we'll see if it includes new drivers or not.

  • cryptomagic Level 1 (0 points)

    Since rolling back the driver, I have not had a crash in 5 days.  I'm ready to accept that as the solution.

    Have you or anyone else here contacted AppleCare about it?

     

    They may know, but they don't know how widespread it is except by looking at the call logs…

  • Pierre Igot Level 1 (15 points)

    Well, what do you know? Two full weeks after using my hack to install the previous version of the IOGraphicsFamily.kext file, I've just had a KP. One every other week is much better than one every day or even more, but it's still disappointing.

    Pierre Igot-

     

    I wanted you to know that an update has been issued. It is not clear whether it addresses this issue:

    .

  • Pierre Igot Level 1 (15 points)

    Thanks for letting us know! The supplemental update does indeed modify one of the "IO" files, so it might include a fix for the KPs:

     

    Mac OS X 10.8.2 Supplemental Update: Updates IOPCIFamily.kext

  • Mwfadebeer Level 1 (0 points)

    in my case, after having suffered for a few weeks i resolved it by resetting the SMC. That has made the problem disaapear.

     

    Follow these steps.

    Sadly, I have to report that I have had another kernel panic, five days after installing the OS X 10.8.2 Supplemental Update:
