有关ubuntu11.04不能正常关机或重启的解决方法

Open a terminal and type:
Code:

sudo modprobe -rf rt2860sta

Followed by:
Code:

sudo modprobe rt2860sta

Then you need to blacklist the wrong driver:
Code:

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 Linuxexperte for this fix.
