I've the same issue with wakeup after suspen to ram on laptop fujitsu A555 with Intel+ATI graphics. It started after updating to kernel 4.4.0.11 and lasts even with kernel 4.4.0.34. Usually, first wakeup works fine, but 2nd freezes the laptop - screen is not black but shows the Desktop and opened applications, keyboard does not responce (switching to console is not possible, reisub does not work also), system fun works and temperature grows. I have to press and hold power button until laptop turns off. Workaround with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.modeset=0" does not work for me. Swap is located on separate primary not encrypted partition.
The latest kernel which works OK with resume from suspend is 4.4.0.10. So, I'm using it. But still wait for a fix. -- 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.
