I have been using aes and not seeing this. I suppose it's unlikely that
there could be an error in the kernel crypto, but I think I'll wait and
try blowfish on a non-critical machine.
My solution has been to not use cryptofs, it crashes with whatever
algorithm I choose :-(
I agree that something is very broken, though. Mind you, I can only
replicate this problem on one of my machines - the other one I've tried it
on seems to work fine. Odder still, when I compile a kernel on the machine
which is fine and ruin said kernel on the machine which is not fine, I
don't experience the crash.
I've attached a traced session plus the config used, may it be of use to
someone (please! :-)
