Yeap, keeping watch on the thread and working on a patch to dump more
workqueue info on sysrq (I don't know which sysrq alphabet to hang it
on yet, mostly likely it'd get appeneded to tasks dump). For all
three subsystems, for-3.17 pulls contained quite a bit of changes.
I've skimmed through the commits but nothing rings the bell - I've
never seen this pattern of failures in any of the three subsystems.
Maybe a subtle percpu bug or cpuset messing up scheduling somehow?
Anyways, let's see how 47dfe4037 does.
