I don't see how that particular bug was related to debug options?

I never felt confident about our understanding of that bug, I did not
get answers to some of the things I asked early on, but then this:


seemed to match a bug I was later able to reproduce and explain in
detail, and could be triggered by the renaming or renumbering of devices
forming a ZFS pool.

I'm slightly in favour of doing this anyway.  I'd hope that having tried
an experimental kernel with debug options for a while is better than
risk a kernel going through experimental/unstable without having done
this at all.  There is still time to fix something or file RC bugs
before it transitions to jessie.
