x220 updated to 10.13.6, stuck at apple logo

Been happily using High Sierra on my Thinkpad x220 for half a year now. Decided to finally update to get rid of the nag today and it booted up fine at first. Installed the fix for USB ports and updated kexts and now I'm stuck at the apple logo on boot. Verbose mode gives me

ACPI Error: [SB_.PCI0.EH02.URTH.URMH.PRTC] Namespace lookup failure, AE_NOT_FOUND (20160938 /dswload-292) ACPI Exception: AE NOT FOUND, During nane lookup/catalog 20168938 /psob 289)... ACPI Error: 6 table load failures, 1 Success ful 20160930 /tbxfload-342)

full error text

I'm new to Hackintosh and googling for the past couple of hours hasn't gotten me anywhere. Any help would be appreciated!
