Hi

 

I am facing system hang issue.

 

BSP is Yocto with 3.10.17-1.0.0_GA.

 

[  939.391052] INFO: rcu_preempt detected stalls on CPUs/tasks: {} (detected by 0, t=2102 jiffies, g=35792, c=35791, q=105)

[  939.402018] INFO: Stall ended before state dump start

 

How to fix rcu_preempt?

Thanks

Saurabh
