I have a mid-2009 15" MacMook Pro, with 10.8.2 installed. Periodically, after sleeping my machine, I open it and hit a kernel panic. The logs fail at the AppleIntelCPUPowerManagementClient kext, and I don't see any non-Apple related kexts in the crash log. Any idea what could be causing this? Hardware failure perhaps?

have you done anything to determine whether it is a software or hardware problem? –  Macmaniman Jan 31 '13 at 15:52

Nope, I'm not sure where to start. –  Louis Jan 31 '13 at 18:22
    
I'm experiencing the exact same problem since last tuesday, when I installed the latest Mountain Lion update that corrected some battery flaws from older macs. I had never experienced said flaws, but figured out it was better to update the OS and "prevent" them. Have you installed that update? –  Fernanda Parisi Feb 1 '13 at 15:40
    
Yes, I believe I recently updated. I'd experienced these before, since updating to 10.8, however not as bad as they were they other day (kernel panicked and restarted about 8 times). –  Louis Feb 1 '13 at 15:53
    
Try disabling "Wake for network access" in Energy Saver preferences. I have issues waking from sleep when this is enabled. –  Dolan Antenucci Feb 6 '13 at 3:20

After the panic, do two cold restarts in Safe Mode. (A cold restart is booting up from the system completely off. You can get into Safe Mode by holding down left shift key while powering up.) That is, hold down left shift key immediately after pressing the Power button. You may release the Shift key when you see the radial start to spin. Do this twice then boot into regular mode by booting normally. By doing this you will allow the system to check itself and repair any errors it finds, this also checks and repairs permissions. Restarting clears the memory and therefore any faults stored in memory. My experience tells me a panic is either the volume directories or bad memory (RAM).

If you want to determine whether your panic is caused by hardware or software problems, I recommend you to install Mac OS 10 on a USB stick, it needs to be at least 8 GB. Boot up from it. Now try sleeping. If it's ok, its most likely (99%) a software problem. It may also be your HDD, which is highly unlikely.

If KPs continue after safe boot, then most likely they're hardware related. Run the Apple Hardware Test suite, extended tests at least twice, followed by Rember. See

Recently happened to me on my 2011 iMac. Tried Safe Mode but kept rebooting. Only thing that worked was CMD-R for Recovery and reinstalled Mavericks. Smooth ever since.
