hi all,

I am play maaxboard ,yocto sumo, kernel 4.14, after running 1 days, it crashed! serail debugger can not login in , ssh can not login, after  power again, the syslog shows as the pictures:

INFO: rcu_preempt detected stalls on CPUs/tasks

someone said at here: 

https://unix.stackexchange.com/questions/252045/rcu-preempt-detected-stalls-on-cpus-tasks-message-ap...

is it right?

more detail on how I can do to fix it?

thank you very much.

This is hard to determine what is the problem. kernel 4.14 is old. I would suggest you use newer version of kernel BSP.
