Voodooi2c: Conflicts with ACPIBatteryManager kext

[hrytskivr]

I2C/HID kext conflicts with ACPIBatteryManager kext which makes touchpad "crazy-jumpy" when on battery power, everything goes back to normal when plugged-in though.
I'm using VirtualSMC/SMCBattery kexts instead of FakeSMC/ACPIBatteryManager to avoid this issue.
Any thoughts what might be the cause?

@hrytskivr What's bad for you using VirtualSMC/SMCBattery kexts? Why would you prefer using FakeSMC/ACPIBatteryManager kexts?

[hrytskivr]

I have non-stable boot with those for some reason.
3 times out of 10 won't boot.

Oh that sucks. I take for granted you have:

• FakeSMC removed
• when FileVault 2 is enabled:
  • VirtualSmc.efi present in drivers64UEFI
  • SMCHelper-64.efi removed from drivers64UEFI
• all your kexts incl. Lilu, VirtualSMC and SMCBatteryManager installed correctly to /L/E (not just in Clover/kexts)
• updated all your kexts to latest versions, easiest via Kext Updater
• are running the latest version of Clover
  ?

@LeeBinder
Everything but VirtualSmc.efi present in drivers64UEFI, I though it's necessary for FireVault stuff only

[LeeBinder]

@hrytskivr : oh you are right: "VirtualSmc-64.efi: Advanced Apple SMC Emulator. VirtualSMC.efi module is recommended for boot.efi compatibility when FileVault 2 is enabled"

apparently the Voodoo kext and the ACPI kext use the same BUS, which thus gets overloaded. Read it somewhere on tonymac, so not 100% sure.

I found the solution. Maybe could help, take a look.
