Acer ES1-522 wifi blocked and Fn keys don't work (WMI)

Acer ES1-522 wifi blocked and Fn keys don't work (WMI)

[Samuel Sieb]

I have a user with an Acer ES1-522 laptop and the wifi isn't working. 
The driver detects it correctly, but rfkill says it's hard blocked.  The 
wifi toggle key doesn't have any effect.  The touchpad toggle button 
disables the touchpad, but doesn't enable it when pressed again. 
However, suspend/resume resets the touchpad to working again.  The 
acer-wmi module is loaded and an input device is created.  However, none 
of the listed keys actually provide any output.

I blacklisted the acer_wmi module and now the wifi works.  Is there any 
further information I could provide that would help?

Hi Samuel, 

What is your kernel verion?

And, did you see any messages in dmesg when you pressed those fn-keys?

Thanks

It's running Fedora 24, so the latest kernel at the time was probably 
4.8.17.  I see that a 4.9.5 kernel is available for F24 now, so I can 
try that one if it would be helpful.

I didn't see any messages at all.

Also, on all the Acer laptops I checked, the accelerometer device gives 
the "Operation not permitted" error.  Should I split that into a new 
thread?  It appears to be part of the acer-wmi module as well.

Could you please create two bugs on https://bugzilla.kernel.org/ ? One for 
function key, another one for accelerometer. I prefer to collect debug 
messages/files on bugzilla for reference in the future. Please send bug
number to me after you created it.

On the other hand, please attach your acpidump result on bugzilla:
 # acpidump > acpidump.raw

I want to check the DSDT table for more detail.

Thanks a lot!

And, please attach your dmesg on bugzilla that it includes messages after
modprobe acer-wmi driver and press the issue function keys.

Ok, but the biggest problem is that the wifi is hard locked with the 
module installed with no way to turn that off.  I'll file a bug for that 
as well.

Sorry for the delay.  I don't have physical access to the laptop right 
now, so I had to wait for someone to make it remotely available.

Wifi hard block: https://bugzilla.kernel.org/show_bug.cgi?id=193751
accelerometer: https://bugzilla.kernel.org/show_bug.cgi?id=193761

I will create another one for the function keys when I am on-site again, 
but that won't be for at least a month.

Thanks for your help to create bugs. I added comments on bugzilla.

> Wifi hard block: https://bugzilla.kernel.org/show_bug.cgi?id=193751

For this issue, please try Chris Chiu's patch:
	acer-wmi: Inform firmware that RF Button Driver is active

For this one, please try this patch that it's merged to testing branch:
	platform/x86: acer-wmi: setup accelerometer when machine has appropriate notify event
