Doesn't the bootlog dump from Clover show the same thing:RehabMan once explained that MSR 0xE2 is a write-once lock. When BIOS initializes, it triggers the lock, which remains locked for as long as the machine is on. It cannot be unlocked except with a reboot. The only solution, if one can call it a solution, is to modify the BIOS.
When we enable AppleIntelCPUPM and KernelPM, the AppleIntelCPUPowerManagement kext is patched to avoid touching the MSR 0xE2 register. Clover auto-detects and applies power management patches as well, which we can see from the Clover log
0:101 0:000 MSR 0xE2 before patch 1E008000 0:101 0:000 MSR 0xE2 is locked, PM patches will be turned on 0:101 0:000 MSR 0xCE 08080838_F1012400
