I am testing my build kext by kext, setting by setting, and .aml by .aml. mouse still laggy will post the results. shutdown now working again. (so far).
can you explain what each SSDT is in detail under the EC section?
What BIOS settings did you set?
You should be able to turn
SetupVirtualMapoff (I only required either that or
RebuildAppleMemoryMapwith BIOS 2.00)
