I only need one set of files that represent what you're doing TODAY.

DW1820A works in LivaCore, and also works on Yosemite in my elite book 1020 (now I am using this it to post).
But on El Capitan it has some problems, occasionally can work little times.
I collected some debug files on both device.

Read post #1, "Problem Reporting".
Files must be for only one computer, not two different ones.
Also what do you man by "occasionally can work little times"?

Note: Not convinced your profile is an ACPI issue.

Files of other computer are used to see why other computer can work (both ioreg and dmesg).

I still suspect it is may be an ACPI issue.....Let me explain:
DW1820A works on Linux & Windows - not a hardware problem
It works on Yosemite in HP 1020 - so the fact and vid/pid are OS X compatible
It works on 10.11.x in other device - It is OS X compatible true
Why it cannot in HP 1020 when running 10.11.x? Must be something different! I disassemble AirPortBrcm4360 using
Code: 
$ otool -tVX AirPortBrcm4360
And note call route corresponding to dmesg...

Look in 1020 DSDT for code that might be dealing with the WiFi.

I had read ACPI 6.1 specification, also read acpica user guide and programmer reference.
After go over code related to WNIC in 1020 DSDT, also compare code related PXSX in LivaCore DSDT, still cannot find something useful.
So I disassemble AirPortBrcm4360 to see which code/function interfaces ACPI/OSL, to figure out which hardware parameters is lack/incorrect to cause DW1820A failed to work.
Does ACPI-Debug is helpful in this scenario?

If you had specific things you wanted to know (variable contents, code path, etc), then you could use ACPIDebug to find out about them.

Is it possible to copy 10.10.5 AirPortBrcm4360 (IO80211Family.kext) to 10.11.5? Or copy 10.11.5 Broadwell Graphics kext (AppleIntelBDWGraphics*.kext) to 10.10.5?

It is possible to copy them, but they probably won't work.

- When running installer
- After sleep
- reboot previously from Linux/Windows
These scenario it works, never try to repeat those.

So the real problem is related to ACPI or other component?
