It doesn't seem to happen on 4.4, it starts somewhere before 4.5-rc1. I
tested the arm64 branch that we pushed upstream with the irq stack
changes but it didn't trigger. It could as well be a combination of
multiple change or just something else.

We'll do some bisecting, though it's not that fun going through the
merging window commits, especially since many are based on 4.4-rcX (we
could try on merges only first, there are fewer).
