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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1566302 Title: Ubuntu 16.04: Suspend freezes the system after upgrade to linux image 4.4.0-16 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1566302/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
