For those who like me have an issue (blank screen and d2 code on qled) there is a solution posted by apfelnico in a .de forum. The issue is due to asmedia usb controller. He made a kext to solve the issue and this work both on Prime and Sage. I tested it and it works! I modified the original x299usb.kext and added the part of asmedia controller.
Here is the source kext by apfelnico and my modified.
Thanks to apfelnico for the source kext.
Do they resolve the USB drive disconnection problem/warning when the machine goes to sleep? I get the same warning for my thunderbolt drive, the drive will reconnect by itself when the machine wakes up...

The purpose of this kext is to solve an issue with BS when you restart the machine...i think it's not related to sleep/wake up issues. It was made for Asus board and i don't know if it works with Asrock

Thanks for the clarification, @thenightflyer! Is the USB drive disconnection error message a common Hack issue or just with my EFI?

Not on Big Sur full time yet, but works in Catalina too.

Ok just moved to 11.1 Public Beta officially on the main Hack/machine. So far it's good. Was a clean easy update (4 reboots) from Catalina 10.15.7 > 11.0.1 Retail > 11.1 PB.

I know I broke my promise of jumping on a macOS update too early, but couldn't help myself since my MacBook Pro is already on Big Sur anyway.

Now the debate is if I should get a 6900XT (when/if there will ever be stock in December's launch) + a EKWB Waterblock and sell the Radeon VII...but I think the ARM Macs are obviously here to stay and I want to step away from Hackintoshing in general, but the only one worth getting for me is the 2020 iMac, but the 5700XT needs to be updated to 6000 series. Decisions decisions. Maybe it's worth hanging on the Hack until later next year for any powerful ARM Macs. The 13" MacBook is compelling but not for me, I need 1) Raw CPU power 2) Raw GPU power. The optimized H264/H265 stuff doesn't help me at all except for transcoding once in a while, I'm mostly in the Adobe suite on the design/motion graphics side and use hundreds of plugins.

i will update to big sur and share the EFI
Do you upgraded to BIG SUR? Can EFI share? Thank you!
The main problem of my ASUS APEX motherboard and EFI is not solved
1) Power management is not perfect
2) Can't use Apple Bluetooth keyboard to wake up,
3) Sometimes the Bluetooth keyboard loses connection after restarting and waking up

Hi, while installing Big Sur I am facing a reboot loop issue. Is there any way to solve other than, install Big Sur on another machine, then transfer the drive? I am using the OpenCore 0.6.3.

I need a quick recap about Asrock X299 Creator we both have
Did you manage to :
- have NVRAM working ? witch SSDT do you use to archive that?
- directly Update from Catalina to Big Bur on internal SSD or Nvme ?
Thanks

Use VirtualSMC and get rid of FakeSMC.
