The 1.6.5 uses different code here (it reads device directly when decrypting keyslot) and it need more user friendly error messages here, my bad... Anyway, seems like in both cases read of device really returns I/O error while reading keyslot area. Could you send me strace of the command? (No need to enter correct password at all.) BTW if not already there, it is another nice item to FAQ - warn people that strace and similar debugging output can easily leak keys or passwords.

Could that be the problem? Don't think so... kernel should use own includes while compiling and what's failing here is just plain read (I think). > I usually run testing, except that I really do not want systemd, > so until I am sure I can do that update without getting that > atrocity, no update to jessy for me. There is a lot of discussion about this on debian devel, IIRC systemd-shim is possible the way to avoid systemd as init. (dunno if this will be supported). > Anyways, if we do not figure this one out, I will just stay > with 3.10.x, it is a longterm-kernel after all.

You are using MD device - what kind of raid is that? (lsblk -t can say more info about storage stack topology as well).
