I have the same problem with Linux kernel 4.4.8 on my fresh (bought 4 days ago) HP notebook 17-y011nc, with AMD/ATI Topaz XT [Radeon R7 M260/M265].
The interesting thing is, that originally I had the 4.4.0 kernel from Ubuntu 16.04.1 LTS but it sometimes got frozen during suspending. Not everytime, just sometimes. However, it was a way too often, so it was pretty annoying. Then I have found somewhere in forums, that this bug was resolved in newer kernels, so I switched from 4.4.0 to 4.4.8. And it surely was resolved, however after resume from suspend, it ALWAYS got frozen, so my problem in fact got much worse with the kernel upgrade 4.4.0 => 4.4.8. -- 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/1589379 Title: System frozen after resume, on Ubuntu 16.04 kernel 4.4.0-22 Status in linux package in Ubuntu: Triaged Bug description: Problem on HP probook 450, with Radeon R7 M260/M265.
