[arch-general] can't unlock a luks encrypted partition. (urgent).

[solsTiCe d'Hiver]

i am beginning to think there really is a problem.
i have a luks encrypted partition that i automatically mount at boot
via /etc/crypttab with a *keyfile*

so this has never failed and it can't fail except if the keyfile is
damaged.
and today the luks partition failed to be opened  for the *first* time
*ever* by cryptsetup because of a password problem.
once i rebooted it worked.
so the keyfile is not wrong. and i double check it with my backup
keyfile

this looks like your problem Hussam. it sometimes fails sometimes works.
