Re: Diagnosing ACPI trouble related to pinctr_cherryview on 4.8.x

[Martin Langhoff <martin.langhoff@xxxxxxxxx>]

About a year ago, I tried to get this laptop going with Fedora's 4.4
kernel, and we had this thread -
http://www.spinics.net/lists/linux-gpio/msg13139.html

Now I have that laptop back, and it only boots with the custom-built
4.4 I prepared back then.

The exact same behaviour is observed with 4.8.x (4.8.15 from latest
Fedora at the moment). Won't boot. Disabling ACPI won't do it.

Has there been any progress on pinctrl_cherryview, is there perhaps a
branch/tree with new configs I should test?

cheers,


martin
