Hello,
I can’t shutdown my laptop on openSUSE Tumbleweed (20151111) anymore.
It looks like the issue is related to kernel 4.3 and to my encrypted /home partition (luks + xfs). The log says:

(full shutdown log here: http://paste.opensuse.org/45620814)
With kernel 4.2.4, it shutdowns fine.
I don’t know how to debug this, any help appreciated
