You have been subscribed to a public bug: This started happening after I upgrade to ubuntu 18.04.2. In 18.04.1 hibernation was working flawlessly on my machine. (with kernel 4.15-46! not a kernel issue then?)
Another thing that got updated recently was nvidia drivers which were known to cause hibernation issues, but those were on restoring the snapshot. http://imgur.com/gallery/jOyHEcL --> I get stuck on this screen after running hibernate or pm-hibernate. (sys-req REISUB combination works there and is the only good way to restart I found) SPECS Laptop Dell Inspiron 7567 A30P Intel Core i7-7700HQ 1x 16 GB DDR4 1 TB HDD + 256 GB SSD Nvidia GeForce GTX 1050 Ti FHD display Intel Dual Band Wireless AC 3165 1x1 Motherboard: Intel HM175 Graphics adapter: NVIDIA GeForce GTX 1050 Ti (Laptop) - 4096 MB, Core: 1620 MHz, Memory: 1752 MHz, GDDR5, 21.21.13.7320 (ForceWare 373.20), Nvidia Optimus nvidia driver: 415.27 INFO # uname -a Linux matheus-Inspiron-15-7000-Gaming 4.15.0-46-generic #49-Ubuntu SMP Wed Feb 6 09:33:07 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux # free -m total used free shared buff/cache available Mem: 15906 2925 8742 161 4238 12485 Swap: 16333 0 16333 # cat /etc/fstab | grep swap # swap was on /dev/sda8 during installation UUID=70d967e6-ad52-4c21-baf0-01a813ccc6ac none swap sw 0 0 n root@matheus-Inspiron-15-7000-Gaming:/home/matheus# cat /var/log/syslog | grep hibernate root@matheus-Inspiron-15-7000-Gaming:/home/matheus# cat /var/log/syslog | grep hiber root@matheus-Inspiron-15-7000-Gaming:/home/matheus# cat /var/log/syslog | grep s2disk root@matheus-Inspiron-15-7000-Gaming:/home/matheus# cat /var/log/syslog | grep hibernation I could find nothing scrolling up on syslog about the hibernation process or with grep.... An interesting Note is that if I run hibernate just after I boot, it works and resumes perfectly! But after some system usage it randomly has that problem if I try. The percentage it freezes at is also random, sometimes 0, 1 even 30 once. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: hibernation s2disk suspend-resume -- s2disk freezes at saving image to disk (hibernation) https://bugs.launchpad.net/bugs/1819915 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
