I recently upgraded my Crosshair VI Hero to the latest firmware (version 8101) and in general everything is fine.
However, after booting into Windows the white LED will remain on and the board shows code 9E (TPM related?).
I am running Windows 11 and did not experience this issue before my firmware was upgraded.
I have Fast Startup and Fast Boot disabled, CSM is also disabled and Secure Boot is enabled for Windows.
Yesterday I rebooted once, after updating my AMD RAID software and the light didn't stay on that time.
This morning it remained on after a cold boot and I also tried restarting and another cold boot, but it's still on.
