Comet Lake CPU kernel panic (Big Sur installation boot)

Hello everybody,

 

I've been trying to install Big Sur in my brand new desktop (i5-10400, Asus h470, igpu) following to the letter the dortania guide for this platform with no luck.

 

I always get stuck at this point. It appears to be a CPU related. IoPlatformPanicAction -> AppleSMC and the Fault CPU is the only thing I can get anything to work with. I'm using iMac20,1 as advised, and chose the BIOS settings suggested in the guide (except for Execute Disable Bit, which is not present as an option).

 

Anyone has a clue? Thanks in advance!
