[O. Hartmann]

Hello.

The target host is a

Fujitsu Esprimo Q956
Firmware V5.0.0.11 R1.26.0 for A3413-A1x
Date 05/25/2018
BIOS Revision 1.26

FreeBSD 11.2-RELEASE and 12-CURRENT (ISO Image from 9th July 2018, r336134) are
spamming the console with an annoying error:

Jul 13 10:00:32  kernel: Firmware Error (ACPI): Failure looking up

kernel: ACPI Error: Method parse/execution failed \_TZ.TZ00._TMP, AE_NOT_FOUND

looking up [\_SB.PCI0.LPCB.HEC.ECAV], AE_NOT_FOUND (20171214/psargs-503)

The error is repeated endless.

Can this be fixed?

Thanks in advance and kind regards,

Oliver
