Hello,

I am using Unraid 7.2.0 on the F8 SSD Plus with BIOS version MADN0301.V07. When the system boots I see the following ACPI BIOS Errors in the system log:

Code: Select all

It seems minor, I have not noticed an impact on functionality. Does this require a fix in the BIOS ?

This is a compatibility error caused by irrelevant content from the BIOS and the kernel. They do not affect the normal operation of the system.
