printf Error on High Sierra Install

[CurlyParadiddle]

Hi all,

So I'm upgrading from 10.11 to High Sierra, and I've run into a problem. I made it to the installer screen with only minimal issues (I needed to use the MATS table-dropping fix), but once my system rebooted after the install screen completed, I now can't start up. When I select the "Boot macOS Install Prebooter from Preboot" option, I end up with the printf error. However, when I try to boot into "Boot macOS from [my primary drive]", I get a kernel panic ("Please go to https://panic.apple.com to report this panic"). Booting into the recovery partition works, and the recovery screens I see look like High Sierra's visual style (and when I try to choose a startup disk, my primary disk is listed as having 10.13 installed).

I've tried the OsxAptiov2 fixes listed here (and tried to calculate a slide value for the "slide=0" command, but couldn't get a valid slide value since I'm not getting an "error allocating x pages" error). Searching the forums hasn't helped either. Anyone have any ideas? I'm currently running Clover 4392

I've now tried installing and reinstalling High Sierra a number of times. Most recently, I tried using tonymacx86's custom Clover build to install OsxAptioFix3Drv-64.efi, but I'm still getting the same error. Attempting to boot into the Recovery partition gets me the "kextd stall AppleACPICPU" error. Anyone have any ideas?
