Description Zhang Rui 2019-05-23 02:25:48 UTC

On Toshiba Z830, GTF0 control method is not defined but referenced by other control method, this results in a couple of ACPI error messages during suspend/resume.

$ grep GTF0 *.dsl
ssdt1.dsl:    External (GTF0, IntObj)
ssdt1.dsl:                Store (GBU0, GTF0) /* External reference */
ssdt1.dsl:                Return (GTF0) /* External reference */

And the error messages are
[   35.737369] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.SAT0.PRT0._SDD.GTF0], AE_NOT_FOUND (20190215/psargs-330)
