Linux on Xilinx zcu102 crashes "nwl-pcie fd0e0000.pcie: Non-Fatal Error Detected" error

I made a petalinux project with Xilinx 2018.3 sdk environment. I built my project upon a zcu102 Xilinx board, and a PCIe card attached to that board. I debug my code for some time without error, until it crashes. it happens after I run external simulator that send data to the pci card. see the photo. I get endless massages: > [ 1845.777165] nwl-pcie fd0e0000.pcie: Non-Fatal Error Detected The error is running on my console continuously and by that time sdk [eclipse] is also stuck and I need to power cycle the board. What does this error mean? I will provide more details if necessary. Can you suggest a way to debug this error and get to the root cause?
