Hi All,Many thanks for your help. You're right. It was something wrong with my last bisect. I did another bisect. I evaluated the one "sometimes boots" with good.

---- git bisect good Output: 0d0b4c866bcce647f40d73efe5e90aeeb079050a is the first bad commit commit 0d0b4c866bcce647f40d73efe5e90aeeb079050a Author: Jiang Liu <[email protected]> Date: Mon Jun 1 16:05:12 2015 +0800 genirq: Introduce struct irq_common_data to host shared irq data With the introduction of hierarchy irqdomain, struct irq_data becomes per-chip instead of per-irq and there may be multiple irq_datas associated with the same irq. 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.
