Flashing the recent BIOS update (FBKTA5A released 2015-01-06) resolved the
problem for me:
http://support.lenovo.com/downloads/ds035753
Shutdown works now with kernel 3.13.0-44.
As I did a bisect from 3.13.0-43 to 3.13.0-44 before I did the BIOS
update here's the result anyway:
01414f897d20874f6f5d7ef2f756f5bf2df526fc is the first bad commit
commit 01414f897d20874f6f5d7ef2f756f5bf2df526fc

xhci: Switch only Intel Lynx Point-LP ports to EHCI on shutdown.

commit 0a939993bff117d3657108ca13b011fc0378aedb upstream.
Patch "xhci: Switch Intel Lynx Point ports to EHCI on shutdown."
commit c09ec25d3684cad74d851c0f028a495999591279 is not fully correct
It switches both Lynx Point and Lynx Point-LP ports to EHCI on shutdown.
On some Lynx Point machines it causes spurious interrupt,
which wake the system: bugzilla.kernel.org/show_bug.cgi?id=76291
On Lynx Point-LP on the contrary switching ports to EHCI seems to be
necessary to fix these spurious interrupts.
