Hey, so I tried to patch my X220 SSDT and DSDT using Rehabman patches and I encountered this issue:
https://github.com/RehabMan/Laptop-DSDT-Patch/issues/93

Also before I tried to patch HPET using SSDTTime, but program patcher seems to be broken and is not finding my HPET device:
https://github.com/corpnewt/SSDTTime/issues/7

Still, I need to patch quirks in SSDT and DSDT to not only get working correctly HPET device (for VoodooPS2 and AppleALC), but also I want to have working battery and brightness control.

I use MaciASL from here:
https://github.com/acidanthera/MaciASL

My dump was done from Arch Linux using SSDTTime (iAsl) but is the same when I dump it from Windows (I have triple boot).

Not sure how can I fix it. Any ideas?
