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

[Martin Langhoff <martin.langhoff@xxxxxxxxx>]

Hi Mika,

this is... interesting. I've recompiled Fedora's v4.10-rc7 with
pinctrl-cherryview=m. Now all it needs to boot is 'noacpi'.
Blacklisting pinctrl-cherryview makes no difference.

Diffing the config made no sense, as you're using a minimal config and
I'm using distro config. The diff was awful.

I'll capture dmesg and compare.

Is there anything we can do to make pinctrl-cherryview better behaved
when built in? I mainly want this laptop to work well with the distro
kernel :-)

cheers,


martin
