[Vincent Gerris <1542939@xxxxxxxxxxxxxxxxxx>]

I have random freezes on:
Linux vincent-Lenovo-Yoga-2-11 4.4.0-15-generic #31-Ubuntu SMP Fri Mar 18 19:08:31 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I can switch VT without problems, but I have had lockups now for 5 times.
I hope this "stable" version will have that fixed before the kernel freeze date.
Another risk of losing users Ubuntu!
