If it is kernel, there must be error message in syslog (use some kernel
parameter to display log to console, depends on used init system).
It looks like that some module is missing in initramfs...
(Unfortunately all I get from kernel device-mapper if it fails is -EINVAL,
that's why userspace cannot sometimes display better info.
Anyway, running cryptsetup with --debug can provide more info as well.
