Sounds good. There were some  bluetooth bug fixes between 4.1 and 4.2 so
good chance that this solved your problem. Closing this bug for now.

Title:
  system freezing with bluetooth sony vaio mouse

Status in bluez package in Ubuntu:
  Fix Released

Bug description:
  Hello,

  I am testing Ubuntu-gnome 15.10... For this, I installed Wily in my
  notebook Sony VAIO SVS151290. I bought this notebook already with a
  Vaio integrated bluetooth mouse from Sony.

  While I used the Vivid I could use the mouse normally but after I did
  a fresh install of Wily, I began to realize that Ubuntu started to
  freeze completely, so that I am forced to shut down the notebook for
  it to return to work. Ctrl+Alt+F'n' does not work, 'Caps Lock' does
  not work,' Num Lock' does not work ... the computer stay completely
  paralyzed showing the frozen screen with content that was running just
  before freezing.

  At first I thought it was some crash that could be linked to the new
  kernel 4.1.0-3, but then one day, I had to put the mouse to recharge
  and I noticed that the Ubuntu worked normally throughout all the day.

  From there I started doing some tests and found that the crash only
  occurs when I use the Sony VAIO mouse... If I do not to connect the
  mouse and use only the touchpad, everything works normally without
  freezing.

  Every new update of Wily I've been redoing the tests but so far, the
  freezing is still occurring.

  Thank you very much!
