Hi All,
we are running PREEMPT_RT 3.14.36-rt34 on a imx6 board which works really fine.
But we see the following trace when we run this very simple app over ssh :
#include <stdio.h>
int main(int argc, char *argv[]){
int i=0;
while(1){
printf("loop : %d\n", i++);
}
return(0);
}
after a few minutes kernel crash with this message :
Does anybody have any idea on how to solve this?
Thank you very much for all help on this questions.
Regards,
Alexandre

I tried to see if I could reproduce this on my ARM board, but my
snowball board is dead, and my beaglebone white, for some reason wont
boot 3.14 (vanilla or -rt).

Can you try 3.14.39-rt37. There has been some fixes in the vanilla
stable tree in this code. I don't know if it will help you, but it may
be worth a try.

Another thing to try is 3.14.36 without -rt.

Thank you for your prompt reply.
I tried to see if I could reproduce this on 3.14.39-rt37 and 3.14.36 without -rt , and both still crashes. But if I send console msg into a netcat pipe, ./gtest_msg_kernel_oops | nc 192.168.44.180 1234, i don't get the crash message anymore.
Best regards
Alexandre

OK, so this is not an -rt issue, it's mainline.
