ok, to not confuse which patch version people are testing,
let's use the version in Alasdair's DM repo now (upstream queue):
http://www.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/dm-crypt-scale-to-multiple-CPUs.patch
(it should be the same as v5/v6 here on dm-devel -
Andi's patch + my changes for device stacking deadlock)

The same patch (just with minor define fix) is reported rock solid for 2.6.36.
