perhaps you should remove blkio from the cgroup if you do not use it as
it seems to be from my point of view the culprit as this is what
appeared on those versions. As all my servers are vserver patched i
really do not know if this is related to cgroup/vserver i never been ale
to have a valuable trace on this issue. 3.0.28 is pretty recent one so
this is curious.

this is how i use it most of the time ^^ hardware issue free migration
and i keep ssh access even if the guest is hacked...

disbale no but remount it with blkio disabled to see if it helps.
