Hi, paul,
is this a regression? if yes,  can you please attach the dmesg for old good kernel?

I do not think this is a regression.

This is an error within the firmware. SMIC and SMIB are both declared in the DSDT and an SSDT in your acpi tables. This is probably not a serious issue. If you would like a fix, I suggest contacting the firmware vendor. Closing, this is a bug in the firmware, not in the Linux kernel.
