ACPI gpe4E Storm - MacbookAir 7,1 (early 2015)

Hi arch community,

maybe someone can run the following command to see if it's normal:
running this

 grep . -r /sys/firmware/acpi/interrupts

i get this

gpe4E and sci are very high and rising all the time. My battery dont last as long as with Debian Jessy. Only 5-6 hours instead of 8-10h. I tried this :

 sudo sh -c 'echo "disable" > /sys/firmware/acpi/interrupts/gpe4E'

this disables the interrupt BUT the number of interrupts is still rising wether its disabled or enabled.

Can someone please help me or try it on their own Macbooks?

kind regards           crimp2333

Re: ACPI gpe4E Storm - MacbookAir 7,1 (early 2015)

what have I done wrong? Why is nobody answering?

Edit:
I found a solution for better battery life. I added "acpi_osi=" to the kernel parameters at boot. I don´t know if it's real but my battery life went from 4-6h at (80% Battery) to 10-11.5h at 77% Battery.
Again, it is just shown in the statusbar and maybe not the real battery stamina but it is an improvement!

I try to ignore the gpe4E problem. It is disabled and I hope it is not interfering with my battery or CPU.

Hope this helps others.
