I don't think you have completely removed all traces of 4.2 unstable
when switching back to the packaged version 4.1.

I suggest you use the rpm tools to check for files under /usr which
aren't owned by a package which might be a left over from xen-unstable.

My guess is that you have a libxenctrl*.so somewhere which is from
unstable. xc_acp_op was removed so the acm.so (from 4.1) can't find the
symbol in it
