Comment # 4 on bug 1123342 from Arvin Schnell

My analysis so far shows that the problem happens when there 1. are LUKS
devices on some available devices, 2. entries in /etc/crypttab for
unavailable devices exist, 3. these entries are before the entries of
the available devices and 4. the entries in /etc/crypttab start with /dev
(so do not use UUID= as YaST writes per default (at least since a year)).

So as a workaround you could try to use UUID= in /etc/crypttab.
