Comment 22 for bug 1884981

Thanks! I also realized that chances are better for the touchpad to work if it worked on the last boot. I believe the kernel does strange things with it when it spams me with "controller timed out" messages on shutdown. I wrote a script which prevents the system from having these shutdown issues. It unloads some modules and then reloads them. Unfortunately it only helps for the next boot, the touchpad is never even recognized after running it.

sudo modprobe -r i2c_hid
sudo modprobe -r i2c_piix4
sudo modprobe -r hid_multitouch
sudo modprobe i2c_hid
sudo modprobe i2c_piix4
sudo modprobe hid_multitouch

It helps to break "bad boot streaks"
