I have an issue , this has been an ongoing issue since I bought this board back in Nov of 2021.
I have a 2TB SN850 in M.2_3 and it doesn't detect once in a while. A Reboot fixes the issue.
Some bios have been fine, but it looks like with new bios 2004 its back to not detecting some boots.
I am on Win 22H2 and Bios 2004.
Others have mentioned this before
