Comment 22 for bug 1072163

Michal, you should try the workaround using the wistron_btns kernel module and not with the amillo-rfkill. The amillo-rfkill does not support your hardware (as per your comment #16).

The wistron_btns, on the other hand, implements the same functionality as the old fsam7400, so it should work fine with the workaround. Without the workaround, it will crash as you referred before.
