Marek Stasiak, to keep this relevant to upstream, one would want to periodically check for, and test the latest mainline kernel (now 4.9) as it is released.
Could you please advise? ** Tags removed: kernel-bug-exists-upstream ** Tags added: kernel-bug-exists-upstream-4.9-rc5 latest-bios-f5 needs-bisect needs-upstream-testing regression-release ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1641244 Title: Ubuntu 16.04 suspend works only twice or thrice in a row, freezes at next attempt Status in linux package in Ubuntu: Incomplete Bug description: This problem was introduced with Ubuntu 16.04 or rather with kernel 4.4; I never had this problem on Ubuntu 14.04 and kernels from 3.x line. Suspend works only twice in a row, sometimes three times, the next attempt of suspending results in basically dead machine but system fans are spinning, monitor back light is on etc. My problem is similar to #1634446, #1566302, #1574125, symptoms are basically the same. I tried more recent kernels: 4.6, 4.8, but its all the same. The problem existed after upgrading my system from 14.04 to 16.04 and after fresh installation of 16.04. If I recall correctly the problem existed with proprietary graphic drivers (nvidia-367 for my GTX770) and also for default open source graphic drivers. I have an encrypted home folder, 8GB of RAM and 16GB swap partition. I'll try to provide every information needed so please inform me if you know how could I make this bug report better.
