Re: Diagnosing ACPI trouble related to pinctr_cherryview on 4.4.x

[Martin Langhoff <martin.langhoff@xxxxxxxxx>]

Took a few days but managed to get my hands on the laptop again.

A kernel built with CONFIG_X86_INTEL_LPSS=n boots with noapic in the
cmdline. Somehow during the build all the PINCTRL options in the
kernel got switched off, perhaps they depend on X86_INTEL_LPSS?

If I don't add noapic, we crash during boot.

I'm about to lose access to this laptop as I am traveling back home,
leaving it with its new owner...

cheers,


martin
