Hello,

I am porting the Android Nougat on imx6d processor. I am getting the errors as follow on kernel terminal output, 

 

INFO: rcu_preempt detected stalls on CPUs/tasks:
0-...: (4 GPs behind) idle=f93/2/0 softirq=146248/146249 fqs=51465
(detected by 1, t=102982 jiffies, g=50694, c=50693, q=861)
Task dump for CPU 0:
swapper/0 R running task 0 0 0 0x00000002
[<c0c5e078>] (__schedule) from [<c1300000>] (init_thread_union+0x0/0x2000)

 

and  the device is stuck. 

Is it a kind of known issue, for which there is any patch to be picked up ?

 

Thanks,

Taehyuk
