Fatal exception in interrupt zcu102 GPIO PL Interrupt Petalinux

Hi,

  I am using Xilinx Zynq UltraScale+ MPSoC ZCU102 Evaluation Kit and I am newbie for using this board. I'm following this link to generate an interrupt using GPIO switches and turn off a led. The drivers works correctly and the led is heartbeating, when i check /proc/interrupts i get:
