Has anyone successfully set up an encrypted filesystem using loopback
on top of raid5? I am very interested in getting this working,
but right now I'm stuck very early on in the process just getting
raid5 to work.
I am running potato and I've custom compiled a fresh 2.2.18 kernel
with patch-int-2.2.18.3 from kerneli.org. I compiled almost every
kernel option as a module, including the crypto and raid stuff.
Here's the error I get and some more relevant info about my system:

Unfortunately mkraid lies about there being additional info logged
to syslog or /proc/mdstat. I enabled *.debug in syslog and still
get nothing. Is it possible I need to have another module loaded
in order for raid to function? What gives?
Thanks,
