AICPM not loading - System specs in sig

Ever since I switched to Clover as my boot loader AICPM doesnt load anymore. Even stranger: trying to boot with Chameleon again doesn't fix the issue.


Console gives me this:

25.09.13 12:06:28,000 kernel[0]: kxld[com.apple.driver.AppleIntelCPUPowerManagement]: The following symbols are unresolved for this kext:
25.09.13 12:06:28,000 kernel[0]: kxld[com.apple.driver.AppleIntelCPUPowerManagement]: 	_pm_init_lock
25.09.13 12:06:28,000 kernel[0]: Can't load kext com.apple.driver.AppleIntelCPUPowerManagement - link failed.
25.09.13 12:06:28,000 kernel[0]: Failed to load executable for kext com.apple.driver.AppleIntelCPUPowerManagement.
25.09.13 12:06:28,000 kernel[0]: Kext com.apple.driver.AppleIntelCPUPowerManagement failed to load (0xdc008016).
25.09.13 12:06:28,000 kernel[0]: Failed to load kext com.apple.driver.AppleIntelCPUPowerManagement (error 0xdc008016).

What can I do to fix this?


Another strange thing is: Even though AICPM.kext doesnt load, my CPU is switching between x8 and x20 multi (min and max) only, as needed

I found out that I had indeed a different AICPM version installed. I now put in the vanilla ML version.


Now the kext loads, but the system stops booting after wifi initialisation, where it would normally switch to login window, no matter if I use -s or -x switch or both

Try to generate a new ssdt.aml with the attached app. A faulty ssdt could cause your problems. SMBios of MBP 8,2 is near to your system definition.


Have fun.

I fixed the problem by booting using a chameleon USB stick, then installing AICPM.kext from 10.7.3 and now it OS X boots using my default Clover boot loader again. aicpm gets loaded and doesnt throw any errors in console. I'm using MBP 8,3 for smbios


EDIT: According to HWSensors speedstep is working including turboboost
