Subject: 3.19-rc1 refuse connection from bluetooth headset

Hello,

now I installed 3.19-rc1 kernel and my bluetooth headset was refused to connect automatically. I need to start 
connection manually from laptop (and then it working). Before when I started bluetooth headset it automatically 
connected and I did not have to do anything. Now with 3.19-rc1 kernel I need to do connection manually and I see 
error messages in hcidump:

 $ sudo hcidump

(real address of my bluetooth headset was replaced by <HEADSET_ADDRESS>)

Can you inspect why new kernel refuse connection from my bluetooth headset?

I'm still using bluez 4.98 (which is in Ubuntu 12.04), I did not do any update.
