A new version of ssdtPRGen (v12.0) with multi-processor support is now available from my Github repository. It should just work, but you are warned: Didn’t have a lot of time to work on it and I also don’t have all sorts of different configurations to test the script on. I guess that it where you come in handy.
Please report bugs and other oddities over at: https://github.com/Piker-Alpha/ssdtPRGen.sh/issues
Thank you for testing this update!
