The irq is assigned through:
two lines above but the clockevent's irq field was not set.
I did not investigate a lot, but at the first glance it worked because
the code path used by the default kernel configuration (CONFIG_NO_HZ)
does not use this field.
But when using the dynamic irq affinity , I noticed it was set to 0.
