ACPI bad works with Linux


I try works with Ubuntu 18.10, Debian Testing, Arch, Fedora

The kernel loads with options which are on the screenshot.
BUGS (all distros):
1) Fn+F12 does not work (Air Mode / ON or OFF WLAN).
2) Fn+F2/F3 does not work (Brightness UP/Down).
3) The initialisation Power Supply and percentage of battery charge does not work.
4) The turn on or off Air Mode when lid is closing or opening.
5) The Power Management does not work.

If i suspend and wake up laptop then (all distros):
1) The Fn+F2/F3, works (Brightness UP/Down).
2) The initialisation Power Supply and percentage of battery charge, works.
3) The Power Management, works.

But still (bug №1) and (bug №4) does not work.

The kernel does not work with "acpi=Linux" via HP-WMI (all distros).
The kernel works with "acpi=Linux blacklist=hp-wmi" but it's a bad because HP-WMI turn on or off WLAN and Bluetooth.

ACPI tables does not change after suspend and wake up (all distros).


Maybe these bugs via "acpi_rev_override"  which enables on all distros. But I build kernel without this option then ACPI does not work.
