<br>
I have a iMX6 running a 4.9 kernel with a custom kernel driver communicating<br>
with a FPGA over PCIe. The driver is not built in to the kernel but loaded as<br>
a module after complete boot up. During the running of the system, after a few<br>
hours the kernel completely freezes. No kernel panics or stack traces, nothing.<br>
I have access to the serial console.<br>
<br>
In such a scenario what are the ways to debug and try locating the source of<br>
the problem? I am not looking for a solution for my problem but things or<br>
approaches one can go about trying while trying to fix such a scenario?<br>
<br>
Thank you for any pointers in advance.<br>
<br>
Regards.<br>
