 When this happen on boot,the kernel seems hung and will take about one
 or two minuts,then continue booting as normal.Does anyone know the reason?


Google search string: INFO: rcu_sched detected stalls on CPUs/tasks:

First hit: https://www.kernel.org/doc/Documentation/RCU/stallwarn.txt

That's the kernel doc that describes the relevant system.
