Diagnosing ACPI trouble related to pinctr_cherryview on 4.4.x

[Martin Langhoff <martin.langhoff@xxxxxxxxx>]

[resend w/o html, apologies]

Hi pinctrl_cherryview maintainers.

I unsuspectingly bought a laptop for a family member which hits
trouble with pinctrl_cherryview; it only boots with the module
blacklisted or acpi=off .

System is (trying) to run Fedora 23 -- made more difficult by recent
Fedora kernels having the module built-in.

Are there any useful debugging steps I can follow to narrow this down?
Already tried the acpi diagnostics steps (acpi=ht, etc) to no avail.

thank you!
