Description Martin Mokrejs 2017-02-27 00:16:13 UTC

Hi,
  on Asus laptop G552VW with latest UEFI BIOS 3.0 and I have problems, like many others (previous BIOS was 2.81 or 2.18? but seemed same in behavior). I have no keyboard backlight and some Fn buttons do not work. I have some ACPI related errors triggered by those key-presses:

I used acpi_listen to monitor key codes. I used 4.10.0-gentoo kernel with acpi_osi=Windows kernel commandline option.

I was fiddling with the kernel commandline so I will upload all the dmesg outputs so that you can use diff command to inspect the differences. Notably, I tried:

'none changes to the running kernel'
acpi_osi=!
acpi_osi=Linux
acpi_osi=Windows

The acpi_osi=! causes that I loose:
input: Asus Wireless Radio Control as /devices/LNXSYSTM:00/LNXSYBUS:00/ATK4002:00/input/input8

Here is one with previous BIOS 2.18 before an upgrade but based on a bit different .config.

I added acpi.trace_state=enable "dyndbg=file ec.c +p" to my kernel commandline and booted like in 

attachment_id:254937: dmesg-4.10.0-gentoo.acpi_osi__Windows.txt

and pressed all the Fn keys while being in framebuffer console, from Fn+F1 to Fn+F12, twice each.

Indeed, there is only one PRST (Method) in the namespace:

Looks like a BIOS issue to me if the iasl disassembly result was correct.
Please contact the BIOS vendor.

Thanks

Sorry but I got rejected by ASUS support as this is not an MS Windows-based report. If anybody has some contacts there please try to get it fixed your way. Or try to find out how to repeat this under MS Win 10.

Comment 15 Lv Zheng 2017-07-04 01:13:45 UTC

Closing as documented to be a BIOS problem.
