Subject: Possible wireless issue introduced in next-20140930

Hello, everyone.

With next-20140930 my laptop does not work, i.e. after I enter my login 
and password in KDM, the entire system becomes unresponsive and I need 
to reset it in order to reboot (it does not even show the KDE splash 
screen).

It was working pretty fine with next-20140926.

I've also tested with next-20141022 and v3.18-rc1 and no luck.

git bisect pointed me to the commit below [1].  My wireless card is a 
RTL8191SEvA [2].

I need your help to troubleshoot this.

Thanks in advance.

     rtlwifi: rtl_pci: Start modification for new drivers

     Future patches will move the drivers for RTL8192EE and RTL8821AE
     from staging to the regular wireless tree. Here, the necessary features
     are added to the PCI driver. Other files are touched due to changes
     in the various data structs.
