Probably neverAMD 6800xt still not supported.
The mid 2012 Mac Pro doesn't have Big Sur support. Are you using no_compat_check boot flag ? Did you use some kind of patcher to get it to install ?Updated MacPro Mid 2012 running OC 6.7, without problems. Disconnected other OS/Windows drives prior to update, GPU is not apple flashed. Time taken to update 11m30s.

I thought OC0.6.6 or 0.6.7 was mandatory?Flawless from 11.1 to 11.2.3 with Only Updated Kext´s and OC 0.6.3 just 1 Restart and you have to Login to Apple ID again.......
