Why might a Macbook Pro be freezing on resume from sleep?

My Macbook Pro (17" 2.2 Ghz Intel Core 2 Duo, OS X 10.4.11) often locks up when it resumes from sleep. I usually know I'm in trouble when the display brightness doesn't adjust right away. Then it runs for a few seconds until it stops responding again. The pointer works, but that is about it.

"From your kernel panic log:

Kernel loadable modules in backtrace (with dependencies):
dependency: com.apple.iokit.IOPCIFamily(2.2)@0x35ea5000
dependency: com.apple.NVDAResman(5.0.8)@0x3cbde000
dependency: com.apple.iokit.IOPCIFamily(2.2)@0x35ea5000
dependency: com.apple.iokit.IOGraphicsFamily(1.4.8)@0x3cadb000
dependency: com.apple.iokit.IONDRVSupport(1.4.8)@0x3caf6000

That says that either Apple's Nvidia drivers or the Nvidia card itself is causing the computer to kernel panic so it may be a bad graphics card or simply bad drivers.

Now that Snow Leopard is out and you're planning to upgrade you can try an upgrade (which has newer drivers) and see if that fixes your issue. If the issue remains then it sounds like something is faulty with the graphics card and you'll want to contact Apple Tech Support for a repair under warranty (if you're still covered - 1 year with the computer, 3 years if you bought AppleCare)

Is it a GeForce 8600M? The warranty has been boosted to 3 years because of the card having a design fault - see Apple's technote."
