GPIO Interrupt Does Not Work (Killed)

I installed Up Board kernel following the document (https://wiki.up-community.org/Ubuntu#Install_Ubuntu_kernel_4.15.0_for_UP_from_PPA).
I used GPIO as output to Led on and off without any problem. But when i configured GPIO pin (edge file) as "rising" or "falling", the process killed and OS freezes.

Same problem here, but I used the libgpiod to setup the interrupt. I opened a terminal with ctrl+alt+f6 and ran my program, it said BUG: unable to handle kernel NULL pointer deference, then kernel panic.

New linux kernel 5.0.0 solves this.
