FreeBSD 14.3 Running on Asus Server RS700-E12-RS12U ( 2 x Intel(R) Xeon(R)
6517P ) with 2 x 64G installed on each CPU by 1 plate, ignores half of the
memory with message "SRAT: Ignoring memory at addr 0x60680000000" at boot.
You can find first few rows of the booting log bellow.
I'm attaching useful collection data to the PR.
