Comment 3 Lv Zheng 2017-06-26 06:37:47 UTC

CFGD defined in ssdt5.dsl:

It looks like _PSL was executed too early.
Could you upload full dmesg for further investigation?

Comment 5 Zhang Rui 2017-07-02 08:43:50 UTC

dsdt.dsl:    External (CFGD, UnknownObj)
ssdt10.dsl:    External (CFGD, UnknownObj)
ssdt2.dsl:    External (CFGD, UnknownObj)

    Scope (\_PR)
    {
        OperationRegion (PPMT, SystemMemory, 0x5EF67F98, 0x003A)
        Field (PPMT, AnyAcc, Lock, Preserve)
        {
            PGRV,   8,
            CFGD,   32,
    ...

Lv,
should CFGD be declared as External(CFGD) or External(_PR_.CFGD)?

Comment 6 Zhang Rui 2017-07-03 07:25:17 UTC

This is caused by buggy firmware.
External (_PR_.CFGD, UnknownObj) should be used to refer to the CFGD object. 

We can not do anything in Linux kernel. Bug closed.

Comment 7 Jeremy Murphy 2018-02-26 10:58:41 UTC

Erk, I also have this problem. Time to take it up with HP, I guess.

Comment 8 Jeremy Murphy 2018-02-27 11:59:07 UTC

In case anyone else is interested, I've posted a discussion for this on their support forum: 

https://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/ZBook-15-ACPI-Error-in-Linux-kernel-CFGD-is-an-unknown/m-p/6600728

I don't know how much traction that will get but I'm not sure what else to try.
