Kernel Panic After Update to 10.8.5

Without seeing a photo of the KP, I can't offer any ideas.

You should make sure you used the latest Multibeast (Not 5.5.1 or 5.5).

I used 5.5.3. Standby, working on getting a screenie, I have to put it back to make it panic at the disco.

I replaced it and it booted fine, does this look right?

Bradfords-Mac-Pro:~ Brad$ kextstat|grep -y power

12 0 0xffffff7f80940000 0x2000 0x2000 org.tgwbd.driver.NullCPUPowerManagement (1.0.0d2) <7 4 3>
17 0 0xffffff7f818a6000 0x2e000 0x2e000 com.apple.driver.AppleIntelCPUPowerManagement (214.0.0) <7 6 5 4 3 1>

Well, you'll need to get rid of NullCPU* to find out...

But 214 is the one from 10.8.5.

This is something different (not a locked MSR issue). Look at that top line regarding "xcpm mode"...

This has something to do with "Xnu CPU Power Management", some sort of recent kernel change (perhaps having to do with UEFI?) that allows systems to run without AppleIntelCPUPowerManagement. Somehow, when this happens AppleIntelCPUPowerManagment is not supposed to load.

PikeRAlpha has some information on this in his blog.

You might try simply removing AppleIntelCPUPowerManagement and see what happens...

Removed AppleIntel and it boots fine now, and returns the following:

Bradfords-Mac-Pro:~ Brad$ kextstat|grep -y power
Bradfords-Mac-Pro:~ Brad$

You might want to test and see if you're still getting power management. Test sleep, etc. Test PStates using DPCIManager (or MSRDumper.kext or AppleIntelCPUPowerManagementInfo.kext)
 
Hi,

I foolishly updated to 10.8.5 through the appstore, and now this is the resulting kernel panic. I tried booting with -F and -x flags using the regular bootloader and booting of usb. Both result in the same wifi related kernel panic. How can I manually disable the kext when boot into single user mode or is there another way?

Thanks.

Remove your WiFi card and see if you can boot.
