CFGD defined in ssdt5.dsl: It looks like _PSL was executed too early. Could you upload full dmesg for further investigation?

Lv, should CFGD be declared as External(CFGD) or External(_PR_.CFGD)?
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.
Erk, I also have this problem. Time to take it up with HP, I guess.
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.
