ACPI Error: Method parse/execution failed [_GPE._L6F]

I recently built a PC based on Intel's latest Skylake CPU (i5-6500) and Z170 chipset (AsRock Z170 Pro4), and installed Ubuntu 15.10 on it. After setting up, however, I found that the kernel message buffer was flooded with this error message. This is how I fixed it.

jhshi.me

GPE._L6F is the offending process (process?)

I read on the page linked just above:
""Finally, later on that thread, somebody mentioned that we could just disable the GPE.L6F function by echoing disable to a specific pseudo file in /sys directory, hence the solution mentioned earlier.""

Solution mentioned earlier:
This is how to fix it: add this line to /etc/rc.local:

1	echo "disable" > /sys/firmware/acpi/interrupts/gpe6F

/etc/rc.local returns no such directory etc (this fix was posted around 2016)

 

[Condobloke]

Despite my efforts, I cannot disable/mask/whatever, the gpe.L6F file. The file must exist because that is the file named.

If I was to do a complete reinstall it would not solve the problem....because this existed prior to the M.2....so it is not recent

The more reading I do, I come to the conclusion that either a bios update or firmware update is the answer.

This motherboard has had neither in its lifetime

THIS PAGE shows that such a problem existed in 2015. my motherboard is older than that. (approx. 2013)

I have lodged a support ticket with ASRock asking for help

 

[Condobloke]

The reply from ASRock Technical Support?

Hi Brian,

Thank you for choosing ASRock and contacting us.

B150M Pro4 supports Microsoft OS, we suggest installing Win10 to verify.

Thank you,
Sincerely,
ASRock TSD

That kinda sh*t irks me and may very well have soured my views of ASRock from here on out.

I don't normally buy their motherboards, but now I bet I never do.

 

[Condobloke]

Agreed.

However, that leaves me in a position of not knowing what the hell to do with it. Yet.

Hi Brian. I'm not sure I can make sense of this, but here goes: The output on post #4 from your machine shows that gpe6F exists.

brian@brian-desktop:~$ grep . -r /sys/firmware/acpi/interrupts/
<snip>
/sys/firmware/acpi/interrupts/gpe6F: 0 EN enabled unmasked
<snip>

Why the /etc/rc.local command didn't work is puzzling in that case. It occurred to me that since /etc/rc.local runs at the end of the boot process, maybe the gpe files aren't set up in time for that rc.local command to work, so it fails to find the file.

If that's the case, you could try and turn off the gpe6F at the kernel level with a kernel option: acpi_mask_gpe=0x6F
I haven't used this method so I can't say if it would work but I have read somewhere that it has worked from my notes written some time ago. Another note I have is that the term "mask" may work if "disabled" fails. That could potentially obviate the need to turn acpi off altogether, but that may be a forlorn hope in this case. Dunno.

Plaudits for your efforts on this one!

 

[Condobloke]

Thanks Ben.

acpi_mask_gpe=0x6F returned
brian@brian-desktop:~$ acpi_mask_gpe=0x6F
brian@brian-desktop:~$

So I am assuming it has 'taken'..?

Does the same mask code apply to... or perhaps I should ask, should I apply that same mask to GPE._L6F du

[NorthWest]

What I have in notes is writing the option: acpi_mask_gpe=0x6F, to the linux kernel line at boot time. Like, hit e at the grub prompt, add the option, hit cntl+x and boot up with that option in place. Doing it that way only keeps that option for that boot. I had to discover the notes on an old hdd which I had to mount in a computer not in regular use here.

 

[Condobloke]

i have a 'project' at home (with my wife) which will keep me busy for the coming hours...(just imagine....garden trumps computer !)......
So I will resume later today.

Just a thought...would hitting Y after cntrl x and then enter.....save it ??....and thus perpetuate it for all boots ??

Or is that just wishful thinking on my part?

 

[Condobloke]

And...I may need to obliterate the reent additions to the 'quiet splash line' in order to know if this mask has had the desired effect......

In theory using your "mask" line would not affect the power button and its usual ability to turn the pc off ?

 

[Condobloke]

too many questions from me !!!

I will spend time later......change things around and see what happens !

Onward & Upward.

 

[NorthWest]

To make that kernel option permanent, the usual way is to add it in /etc/default/grub to the config (with a space from other options there and within the double quotes):
GRUB_CMDLINE_LINUX_DEFAULT="<option>"
and then update grub with whatever command does that. In debian it's: update-grub. I don't think hitting Y will do it. I think it's best to find out what effect it has from just adding it at a boot as mentioned in post #28 first. If the "mask" works, and/or if adding the kernel option works, then the other functions that acpi controls like the power button would be unaffected ... that's definitely the theory as I understand it.

 

[Condobloke]

I have opened /etc/default/grub, and removed acpi=off noapic"

which then leaves ;
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

I updated grub ; sudo update-grub
and then rebooted. (The power off/reboot still did not work at this point)

From immediately after reboot/restart, I ran: sudo journalctl -b0 -g acpi

NOTE:....AT THIS POINT I HAVE NOT ENTERED THE CONTENTS OF YOUR POST #28

My next post will have the details at #28 :....What I have in notes is writing the option: acpi_mask_gpe=0x6F, to the linux kernel line at boot time. Like, hit e at the grub prompt, add the option, hit cntl+x and boot up with that option in place. Doing it that way only keeps that option for that boot. I had to discover the notes on an old hdd which I had to mount in a computer not in regular use here.......


Doing that now...reboot then hit e at the grub etc etc

 

[Condobloke]

Of Interest....when I rebooted...menu button...shutdown button...choose reboot......it worked !

Hesitated at the mint logo for just a secone or two and then proceeded to reboot in the ordinary fashion

Just to be crystal clear....this is PRIOR to running post #28

Anyway...interrupted at grub, to enter acpi_mask_gpe=0x6F after quiet splash. I left two spaces after splash....there were NO quote marks present, If I go to that line via home/etc/default/grub the quote marks ARE present in the folder opened as root.


Straight after it has rebooted I ran

sudo journalctl -b0 -g acpi

I do not think you are online now Ben, so I will take a leap of faith and reboot again now

Edit to Add: I have not rebooted yet.

I will take a further leap of faith and make that change permanent, by applying your post # 32

""To make that kernel option permanent, the usual way is to add it in /etc/default/grub to the config (with a space from other options there and within the double quotes):
GRUB_CMDLINE_LINUX_DEFAULT="<option>"
and then update grub""

I have rebooted.

All normal....the power button is UNaffected

My /etc/default/grub looks like:

Have I put that acpi_mask_gpe=0x6F ...in the wrong place ?
Should it be on the next line down...GRUB_CMDLINE_LINUX="" .....??

fwiw, when I interrupted the boot at grub and wrote the instruction there, the line I added to (after a double space) looked like this:

linux /bootvm linuz - 5.4.0-104generic root uuid=5c8cbdbd-b1bd-458e-98ef335b9442d8c7 quiet splash acpi_mask_gpe=x6F

and judging by the fact that the power button etc was then unaffected, that must have been the right place.....I think....

 

[Condobloke]

I rebooted. It rebooted as normal !

i interrupted the boot at Grub

Pic of grub screen below......after taking the pic I added acpi_mask_gpe=0x6F after quiet spash (double space after splash)

I then ran: sudo journalctl -b0 -g acpi

This suggests to me that the ' acpi_mask_gpe=0x6F' I entered into /home/etc/default (open as root)/grub ....is in the wrong position ???
To be clear, i opened /home on my desktop ....then file system, then /etc then right clicked and selected 'open as root'...then /default then grub (not grub.d)
arrowed down to the : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash line and added :acpi_mask_gpe=0x6F after a double space after the word splash. I then put the " back again after the 6F

I then updated grub
Sudo update-grub

Why does it spit out so many results? There are more results visible the more 'blocks' of data are printed out......When I close that particular Terminal window it warns me each time there is astill a process running....closing this window will kill it.

Why in the name of all that is holy there are no errors now....beyond me !

I rebooted again and the result was pleasing....very quick.....30 seconds to boot as opposed to 42 seconds previously.......not that I really ever pay attention to boot time....but it was decidedly quicker than normal so I rebooted again and timed it. Wow.

Why the apic_mask_ etc did not have the desired effect before I have no clue.

I am keeping my fingers crossed.

Hi Brian ... good on you! Looks like something positive has happened. The option looks correctly placed to me from your description. I have performed a fingers-crossed in honour of your diligence and hope it works. That ps output looks good.

Well, the PC has been shut down around 8.30pm last night.
Started again at around 11pm....apps opened and closed and browser opened etc etc, Rebooted, Shut down and restarted.......and shutdown via a hard shut down or 2.....etc etc....and various repetitions of all that since 4am this morning.

With the two terminal commands run in between

ps axch -o cmd,%cpu --sort=-%cpu | head

sudo journalctl -b0 -g acpi

Flying colours all the way.
