With the Intel BIOS support for 8 processor sockets with a full complement of NVDIMMS potentially installable, and there are empty sockets without NVDIMMS, there is an extremely large amount of the following warnings: ACPI Warning: Large Reference Count (0x1001) in object ffff99453fc71750, Type=0x0A On a 4 socket system with 4 NVDIMMs there were over 6000 of these warning messages and it has been seem on systems from 4 to 32 sockets. Through some guidance from the BIOS developers and testing, it appears that simply bumping up the threshold for warnings from 0x1000 to 0x2000 eliminates these messages. Changing them to be ACPI DEBUG messages, or even removing them are other options, but it would then defeat the purpose of the warnings as the problem would effectively be hidden.
