Thanks for the help anyway. I will have to dig further elsewhere tomorrow.

I have the same issue that AppleLPC is not loading and i think that power management does not work properly on my Skylake Sierra build.
After 5min idle the system freeze for approximately 30sec because kernel_task has 100% cpu usage.
This is the output from kextstat and kextcache.

HECI should be renamed to IMEI.
And you should probably inject Intel with an ig-platform-id that has no connectors.
USB also appears to be configured incorrectly (UsbConnector values are wrong).
See guide: https://www.tonymacx86.com/threads/guide-creating-a-custom-ssdt-for-usbinjectall-kext.211311/
Probably a good idea to disable the serial port too.

All done but the issue still exists. I do not inject the Intel graphic anymore because i only use the Nvidia card.

Read post #27. Most everything mentioned there not fixed.

I know this is an old thread, but it has helped me on old hackintoshes running High Sierra. For the longest time, I didn't pay much attention to LPC._DSM in my DSDTs. I always assumed that I needed to enable Generate C and Generate P States in my CLOVER config.plist (my systems are all Intel Lynnfield CPU or older). After reading this thread, I modified the DSDT on my old systems to add the "name" string to my LPC._DSM. Note that LPC._DSM is only necessary in DSDT if AppleLPC is not automatically discovering your LPC device and finding a matching IOName in AppleLPC.kext/Contents/Info.plist.
For my desktop with Lynnfield Xeon X3480 / Series 5 Chipset, I added "name","pci8086,3b09" to LPC._DSM (which is defined in AppleLPC.kext/Contents/Info.plist). Without defining "name","pci8086,3b09" in LPC._DSM, the "compatible" string (observed in IORegistryExplorer) was detected with IOName "pci8086,3b06" (which is NOT defined in AppleLPC.kext). Picking the closest match that is defined (3b09) ended up working perfectly for me.
In fact, after editing the LPC._DSM (to add "name") and removing Generate C / Generate P states in the CLOVER config.plist, Hardware monitor shows that my X3480 CPU assumes more multiplier states and allows the CPU to assume a higher multiplier.
NOTE: I selected a model in my config.plist that most closely matches my systems. For my Xeon X3480 system, I'm using model MacPro 5,1. I suspect that this is important, too. I'm hackintosh amateur only reporting my observations - not claiming any expertise.
