You're right. It was something wrong with my last bisect. I did another bisect. I evaluated the one "sometimes boots" with good.

Some per-irq data stored in struct irq_data now may get duplicated into multiple irq_datas, and causes inconsistent view. So introduce struct irq_common_data to host per-irq common data and to achieve consistent view among irq_chips.
