Ubuntu – System hangs on shutdown/reboot, how to troubleshoot?
The problem is with the wireless adapter. To fix it you need to do this:
Open a terminal and type:
“`
sudo modprobe -rf rt2860sta
sudo modprobe rt2860sta“`
Then you need to blacklist the wrong driver:
`echo blacklist rt2800pci | sudo tee -a /etc/modprobe.d/blacklist.conf`
Once you have rebooted (you will need to do a hard power off for the last time.
You will find you can reboot properly. Thanks to Linux-experts for this fix.
