ndiswrapper locks system when disconnecting from wifi network

  • 772

After some hours of fiddling with ndiswrapper I have successfully managed to connect to my wireless network with my network card which sports a Realtek RTL8190 chipset. I'm using Ubuntu 14.04 and the Win XP 64bit driver which came with the network card. However when trying to disconnect from the wifi network or shutting down the system, the system gets locked by ndiswrapper.

System log:
