I've just loaded FreeBSD 14.0 (in anticipation of 14.1) onto a little MeLE tiny PC with a Celeron N4000 processor. It runs, but throws many errors during boot and afterward of the form ACPI Error: No handler for Region [ECF2] (0xfffff800017caa80) [EmbeddedControl] (20221020/evregion-292) ACPI Error: Region EmbeddedControl (ID=3) has no handler (20221020/exfldio-428) ugen0.1: <Intel XHCI root HUB> at usbus0 ACPI Error: Aborting method uhub0\134_SB.PCI0.SBRG.H_EC.ADP1._PSR due to previous error (AE_NOT_EXIST) (20221020/psparse-689) on usbus0 ACPI Error: uhub0: <Intel XHCI root HUB, class 9/0, rev 3.00/1.00, addr 1> on usbus0 No handler for Region [ECF2] (0xfffff800017caa80) [EmbeddedControl] (20221020/evregion-292) ACPI Error: Region EmbeddedControl (ID=3) has no handler (20221020/exfldio-428) ACPI Error: Aborting method \134_SB.PCI0.SBRG.H_EC.BAT0._STA due to previous error (AE_NOT_EXIST) (20221020/psparse-689) ACPI Error: No handler for Region [ECF2] (0xfffff800017caa80) [EmbeddedControl] (20221020/evregion-292) ACPI Error: Region EmbeddedControl (ID=3) has no handler (20221020/exfldio-428) ACPI Error: Aborting method \134_SB.PCI0.SBRG.H_EC.BAT0._BST due to previous error (AE_NOT_EXIST) (20221020/psparse-689) ACPI Error: No handler for Region [ECF2] (0xfffff800017caa80) [EmbeddedControl] (20221020/evregion-292) ACPI Error: Region EmbeddedControl (ID=3) has no handler (20221020/exfldio-428) ...

Apparently, either the BIOS is missing the code to support some specific piece of hardware, or it doesn't NEED any code to support it and FreeBSD's ACPI software is trying to find some anyway. How can I eliminate the errors? --Brett Glass
