HAD Lion 7.2 on Intel P55 Board running fine.
* upgraded Bios
System Crashes during Boot (indicating issue with AppleIntelCPUPowerManagement.kext)
* Reverted Bios to ORIGINAL version

YES, I checked the BIOS setting after the upgrade and subsequent downgrade, to be sure
that the setting were SAME as before.
It seems like a BIOS update changed the way the HARDWARE responds to the
very same SOFTWARE. Bios was updated with Intel universal Bios install on USB stick.
To be SURE, I did this on two different machines and the results were the same.
Yes, if I install /Extra/Extensions/NullCPUPowerManagement.kext
Then I am able to boot, but of course the System is Unable to SLEEP.
I could use some Words of Wisdom by someone who understands the Bigger Picture.
thanks in advance !!
