RE: [PATCH 18/19] ACPICA: ACPI 6.0: Add support for NFIT table.
From: Moore, Robert
Date: Fri May 22 2015 - 11:28:14 EST
Yes, you are correct, the NFIT strings are wrong. For example, the first string for UUID_VOLATILE_MEMORY should be:
"7305944F-FDDA-44E3-B16C-3F22D252E5D0"
You might want to verify this.
We will fix the original patch ASAP.
Thanks,
Bob
