> The issue comes from the Bios implement ACPI AWAC(time and alarm device,
> "ACPI000E") by using the SystemCMOS, and the kernel acpi-tad driver has no
> handler for dealing with it. When it call _GRT: Get Real Time or _SRT: Set
> Real Time, so it will get the "No handler for Region SystemCMOS" and
> AE_NOT_EXIST issue.
