Solved by disabling the xCHI usb 3.0 on the bios. adding parameters to Grub didn“t.
Now Freezes does not happen after suspend, hibernate, close the lip or turning off. It takes a decent amount of time to turn off and the screen flash in different shades of black when booting though. would be nice to see this solved. Hope it helps and that this is the proper place to share this. I had the same problem here on Acer Aspire E15. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1566302 Title: Ubuntu 16.04: Suspend freezes the system after upgrade to linux image 4.4.0-16 Status in linux package in Ubuntu: Won't Fix Bug description: I'm using ubuntu 16.04 on a XPS 15 9550. Suspend/resume worked flawlessly with linux image 4.4.0-15, and after standard upgrade yesterday (5/04/2016) which installed image 4.4.0-16, the system freezes when attempting a suspend. I get no response from the system (nor keyboard, nor screen, nor touchpad), but it gets very hot, so that it must be running something. Booting with 4.4.0-15 makes the suspend to work perfectly.
