SMART data unfortunately is not always conclusive; particularly, it's
not always conclusive in indicating the _absence_ of a problem. Plain
and simple, storage devices _lie_, some more than others.

I would try again, but this time creating the LUKS container using a
file in a ramfs (not tmpfs, which is allowed to be swapped out) as
backing store, possibly mapped to a loopback device. Doing so will
eliminate persistent storage from the equation.

If that works, then my suspicion would be on the drive itself.

If that doesn't work either, then there's likely something problematic
about the software stack, at which point exact versions of everything
becomes interesting. Kernel, cryptsetup, libcryptsetup, ...
