There was some problems with O_DIRECT on ARM architectures
(search archive, I think I posted some links).

Anyway, problem is with using already mapped volume (e.g. swap) or
with using cryptsetup (LUKS header/keyslot corruption)?

I do not thing that it is problem in dm-crypt
Do you have some reproducer? kernel version, syslog messages etc?
