It really sounds as if the tiny-rcu kthread somehow just stops handling callbacks. The ones that keep increasing do seem to be all rcu-free'd (but I didn't really check).
The thing is shown as running:
root 6 0.0 0.0 0 0 ? R 22:14 0:00 \_ [rcu_kthread]
but nothing seems to happen and the CPU time hasn't increased at all.
I dunno. Makes no sense to me, but yeah, I'm definitely blaming tiny-rcu. Paul, any ideas?
