Well, it's problematic for us, the assignment fails here or there on
some of our new systems with the new code multi-pass code for memory due
to the lack of IO which is nasty at best.
We were hoping we could get 3.10 to support those machines since that's
apparently what a well known enterprise distro will pickup (and trying
to get them to pickup backport can be complete hell).
Cheers,
Ben.
