Pci write before a pci read

We have observed some strange behavior during pci communication with the xilinx board (XUP-P3R PCIe FPGA Board).

In the entire bar space if i read from any address the linux computer crashes. 

 

However if i write to any address in the bar space followed by read there is no problem .

What is the reason that i need to write before read from the pci bar space?

Thanks
