Linux error prefetch abort kernel panic

Hi all,

I am using ARRIA 10 SOC for the project with Linux arria10 4.9.78-ltsi-altera #1 SMP UTC 2019 armv7l GNU/Linux, I have written a userspace application for controlling DMA,
My board contains 2 GB of ram in HPS side and I am using Linux kernel only on 800MB and other 1.2GB I have used it for FPGA DMA transfer, sometimes I am getting a below-mentioned error please help me in resolving the error.

Unhandled prefetch abort: external abort on non-linefetch (0x1008) at 0xc0195620
