Hi!
I am running 4.4-RELEASE with a custom kernel. While testing the box under
heavy load it gives kernel panic and reboots. I have included the panic
message and the nm output.
I am not sure if its a bad memory problem, bad driver or bad gigabit card.
I would really appreciate any suggestions or comments.
Let me know if you need any other information.
Thank you for your time and help.
