Acer Switch 12: ACPI errors while booting kernel

Acer Switch 12: ACPI errors while booting kernel

[Nicholas Kudriavtsev]

Hi,

While booting kernel (4.1.3, Fedora 22) I've got errors regarding to ACPI in dmesg:

I filled in a bug report on the subject https://bugzilla.kernel.org/show_bug.cgi?id=102421
and attached acpidump output there.

I know little about ACPI but if someone can make a patch to eliminate the errors (or can prompt me
where and what to change in the kernel source), I can apply the patch and test corrected kernel on
the hardware.
