hdac0: Unexpected unsolicited response from address 0: 00000000

[balanga]

This happens when I boot up a Lenovo Thinkstation M73:-

smbus0: <System Management Bus> on ichsmb0
acpi_wmi0: <ACPI-WMI mapping> on acpi0
acpi_wmi0: cannot find EC device
acpi_wmi0: Embedded MOF found
ACPI: \134WMI1.WQCA: 1 arguments were passed to a non-method ACPI object (Buffer) (20221020/nsarguments-361)

hdac0: Unexpected unsolicited response from address 0: 00000000
hdac0: Unexpected unsolicited response from address 0: 00000000

This is under FreeBSD 14.3-RELEASE.

Anyone know what is causing this and if it needs attention?

ACPI tables are often wacky. If thingie works I wouldn't worry about it. You could try a BIOS update.

Can I get BIOS info using FreeBSD?
