The fact that both use the same device node is expected, yes.  Two
other things you've mentioned are not, though: the fact that iscsi.ko
ends up being not usable, and ctld panics.

Can you show the exact command sequence that leads to the first
problem, ie iscsi.ko being unusable, even though it's loaded?

Do you have a backtrace for ctld panics?

Thanks!
