Issues after upgrading to sequoia: long black screen before login page and volumes not appearing

Hey all, I've been hackintoshing since high sierra and have had my fair share of upgrade weirdness but I haven't seen anything like this before and am wondering if anyone else has.

First, and most annoying, after all verbose output during boot, I get only a black screen for about 3-5 minutes until the login screen finally loads. The verbose phase of boot takes a normal amount of time. Second, I'm not seeing any drives aside from my OS drive (which is really the only one I use on MacOS) - every windows drive + external drive is missing.

I checked my usb ports using USBTool and saw that my flash drive that I'm booting from is being detected in the XHCI port, but it's not showing up in disk util and doesn't show up after executing diskutil list. Other XHCI ports appear to be loading correctly; keyboard, mouse, USB audio devices, etc. are all working properly. I've tried changing smbios to 20,1, 20,2 and 7,1 but to no results, removed boot args, dumbed down my EFI, and these two problems are persistent.
