Yes， some modules don't install by default on our Ubuntu devices. Execute
commands below then run the tests, the result passes.
apt-get install nfs-common nfs-kernel-server
/etc/init.d/client_module
mount -a
root@x-bdw05:/GFX/Test/Intel_gpu_tools/intel-gpu-tools/tests#
./drv_module_reload
unbinding /sys/class/vtconsole/vtcon1/: (M) frame buffer device
module successfully unloaded
module successfully loaded again
root@x-bdw05:/GFX/Test/Intel_gpu_tools/intel-gpu-tools/tests# echo $?
0
[root@x-bsw01 tests]#./drv_module_reload
unbinding /sys/class/vtconsole/vtcon1/: (M) frame buffer device
module successfully unloaded
module successfully loaded again
[root@x-bsw01 tests]# echo $?
