The above errors are actually one error as a result of calling chain: _PTS->ESDT->RCM0, and it fails when accessing RCM0 as RTC CMOS registers aren't currently supported in Linux kernel.

Fortunately, \_SB_.WMID.ESDT is the last function in _PTS and BIOS has completed everything it tends. No or few impacts are generated by the absence of RTC CMOS handling.
