Subject: [ACPI] How to debug immediate wakeup after resume?

Good day hackers,

sometimes when I close the lid of the Lenovo Yoga 2 Pro, it suspends,
but resumes immediately (while the lid is still closed).

I have seen this happening various times and was now able to
capture the dmesg output of it happening.

I am running 3.12.9-2-ARCH and wondering if there is any good way to
find out, why the notebook wakes up?

Attached are dmesg up and including the last sucessful suspend as well
as dmesg output of suspend and immediate resume.

Cheers,

Nico
