I have this problem from the begging. First I installed Ubuntu 16.04 with kernel 4.4.43. I also tried kernels 4.6.* and 4.8.*. None of them solved my problem. I upgraded BIOS to the latest version 1.9.4. I run various hardware diagnostic tests, but found nothing.
I've just tested on kernel 4.9.0-040900rc1.201610151630. Unfortunately bug is still there. ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634446 Title: Ubuntu 16.10 suspend problem on Dell Latitude E5470 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1634446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
