[   82.776820] thinkpad_acpi: EC reports that Thermal Table has changed

alignment

There is nothing in the logs apart from this.

If I execute the suspend by calling systemd directly it seems to work just
fine. But after the lid-close first the previous call must be killed to
actually work.

Also it does not happen on:
vmlinux-4.1.13-5-default.gz

And can be visible on:
vmlinux-4.1.15-8-default.gz

It is one of the T430 we have in SUSE.
