I have spent the past few days attempting to get the installer for macOS Sequoia 15.8.1 to boot on my setup:

The problem is no matter what I do, I never get past this message:
"Registered CoreAnalyticsHub functions with xnu.virtual bool CoreAnalyticsHub::start(IOService *)::229:CoreAnalyticsHub start completed"

By adding io=0x16 into my boot args the very last line that shows into the screen is:
"IOHIDProviderPropertyMerger[0x1000001ba]::probe fails"

I have tried many different configurations, disabling WiFi, Bluetooth, Onboard audio, IOMMU, no SSDTs loaded, SSDTTime-generated ones, a misc of boot arguments (npci=0x2000, -radvesa, -wegnoegpu) and many more tweaks into config.plist to the point I have truly forgotten every one of them. No matter what I do I get stuck at the exact same point.
I'm honestly lost here. I first hoped it would be an SSDT issue, then moved into USB, then CPU core count, nothing helped me.

I'm attaching my current EFI folder. Thanks in advance!

Where did you get the 2 x MmioWhitelist entries in your config.plist?
Did you follow this part of the OC troubleshooting guide when generating them?


Does your system not require any AM5 ACPI patches?
If you post a copy of your System ACPI tables, someone may have a look to see which if any patches your system requires.


You will need a copy of Miele's RTL812xLucy.kext for the Realtek 2.5G Ethernet port to work on your motherboard.

 
I'm confident I must've have grabbed those MmioWhitelist entries from someone else's config.plist (that was showing the same symptom as I am).

I haven't read deep into KASLR but I will do later today after work.
I will also read the 'DSDT patch' post you added and see if I can figure something out.

I'm attaching the complete ACPI dump below, maybe someone can chime in to help.

Thanks!

Quick update. I managed to boot into the installer by applying the three suggested patches on the 'DSDT patch' linked post.

I can format the disk just fine and start the graphical installer, however near the end of the installation the computer locks up (screen says "About 12 minutes remaining" but I know it's nowhere near a reliable estimate). No mouse movement, progress bar sits still.

On a second installation attempt I opened the installer logs and expanded to fill most of the screen to inspect whatever the installer is doing.
I added two screenshots from the logs below.

When the installation locked up I left it there for a solid 30 mins before restarting the PC.

OpenCore itself does not see any boot entries regarding any macOS preboot environment or the installed OS itself.
Just one entry for Windows, the macOS Installer on the USB drive itself and another entry to clear the NVRAM.

I will continue investigating, I'll probably have to keep digging into the DSDT itself to find for any more sections that need patching
