Comment 0 for bug 1231725

I instaled bumblebee-nvidia for Optimus support in my Asus laptop and bbswitch-dkms causes forced shutdown, even if I reboot system. My HDD makes a loud noise, It is as if the power went out, the forced shutdown is very violent. I know that bbswitch is used for turn on and turn off nvidia card, but somehow it is affecting shutdown/reboot.

Steps to reproduce:

- Install nvidia-319-updates (319.49) and bumblebee-nvidia;
- Configure bumblebee files to works with nvidia module;
- Reboot system, bbswitch will be active in the next login;
- After login system, try to turn off the system, or reboot. System will causes a forced shutdown;

There is workaround to avoid this problem, runs:

sudo modprobe -r bbswitch

before every shutdown or reboot.

Please, this is a important (and dangerous) bug, anyone that tries to get Optimus tecnology works in Ubuntu and uses Bumblebee probably will get a HDD broken in a few months of use, without knowing why.
