A new beta bios has been posted on X570 Aorus Master support page and has a mention of "Checksum : D303" in the list of fixes.
New release of 21.5.1 didn't fixed the d3 error code.
I have the same issue, even after disabling and master ask, I get a BSOD and crashes and the next boot cycles fine. Any suggestions?
