I have the same problem on x79t (Chinese board based on B75 chipset, LGA2011, Xeon e5-1650v2, 4-channel ddr3). The problem could not be resolved, but Catalina works with this bootloader. I am attaching my EFI folder and video log.
I need this update, so I want to help in solving the problem as much as I can. What is required of me? I apologize for poor knowledge of English.
We need someone from the developers to deal with this issue. Because such boards are not common in developed countries where developers are located. I am ready to test developments
i have the same problem on x79 like you
if you find a solution please share with us

You need to choose the iMac 15.1 or 15,2 model
@mimixa I tried to use my OpenCore efi with iMac 15.1. I got the same KP as I had before when trying to boot BigSur installer. I could not find a iMac 15.2 smbios. I could boot to Catalina with iMac 15.1 smbios. I tried to look at your efi for help, but so far no luck. Do you have any ideas I might try? I will put up my efi for you to check out. Thanks for your help and time, Johnm

Give me your DSDT table. I will try to help you.
@RemB I cannot get BigSur going on my x99. I can boot Catalina with OpenCore, but get a KP with BigSur. I have upped my efi, two posts back post and am going to upload my unpatched dsdt if you might be able to help me sort this out I would appreciate any info or help. Thank you Johnm

No luck, but thank you. Do you actually have BigSur running on x99? If so, then somehow there are some smarter x99 people that could take your efi and figure out how you are doing it or what we are doing wrong. I will certainly remember to give you props in the end of this. I'm on 10 weeks of unable to boot/install BigSur on my x99 and it is really painful. I refuse to spend a bunch of money until I know this can't be done. Thanks for your help and take care, John

Thanks so much, I'm installing NOW!!!. I had written on the other board that I used another guy's dsdt that you patched, and it worked, crazy, but I wrote you a long double edited post. I'll get back to you later, after my install, and thank you from the bottom of my existence. I've been burned out on this for 10+ weeks my stomach is broken but my heart is much better now!!
