 +<WRAP round tip>
 +**The kernel seems to fail to compile when the following settings are enabled:**
 +  * Networking support -> [*] RF Switch subsystem support
 +    //Solution: Disable RF Switch subsystem support (not needed on CB2 anyways).//
 +  * Power Management options -> [*] Run-time PM core functionality
 +    //Solution: Disable Run-time PM core functionality or apply the following patch.//
