Comment # 28 on bug 956403 from Takashi Iwai

So, one problem is that phy0 rfkill will be never unblocked once when hp-wmi is
loaded.

Could you try to install openSUSE 13.2 kernel on the current system and check
the behavior of hp-wmi and rfkill with it?  You can install the kernel via
zypper install --oldpackage option.
