System running stall on i.MX8 mini platform

Hi, We are using the IMX8 mini as the mainboard,  we found that when system is runing, there would be a 300ms stall which happend frequently. 

To find the reason, we made a test tool just using two threads, which invoke "gettimeofday" to get the time cyclically.

We found that at one point, there was a delay of more than 300ms between the two prints.

 We used the perf sched record ./pthread_test command to obtain the on-site scheduling information, and found that there was indeed a delay of 300ms.

I am appreciated if someone could help me out.

Hello,

Can you isolate this issue, it looks like a application issue.

Regards
