System freeze using sony-laptop-zseries-0.9np8pre3

 

Hello,

I recently formatted my laptop and reinstalled Ubuntu 11.10, I
downloaded the source for sony-laptop-zseries-0.9np8pre3 and added it to
DKMS and installed the module.

Whenever I boot my system with the module, typing or moving the mouse
causes a system freeze that requires a hard reboot. The minute I remove
the module, I can boot and run the OS stable again.

There doesn't seem to be anything strange in the logs that might imply
what's going wrong, I would really like to get this working as the
module adds a lot of battery life and functionality to the install.
