system freezing with bluetooth sony vaio mouse

[Edson T. Marques]

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!

Good news ... I hope!
Now do three days since updated the kernel to version 4.2.0-7 ... Since the upgrade, 3 days ago, I returned to normally use the wireless mouse (bluetooth) VAIO, and, to date, no other case the freezing interface happened.
I think the problem may have been solved.

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.
