> Is the swap space big enough? A good point. This worked on previous versions on Ubuntu with swap (18GB) only 50% of RAM (32GB). I recreated my /swapfile with 38GB and the same issue persists. ie.
$ free -m total ... Mem: 31964 Swap: 38911 > Furthermore, the hibernation failure isn't logged in the dmesg. That's correct. The machine just stalls with a blank screen. It's still awake as is apparent by motherboard lights. It cannot be awoken in any way and needs to cold restarted using power button. Curiously if I run smem before I attempt to hibernate, it does not show any processes using swap. ie $ smem --columns="swap" --no-header | tr -d " " | awk '$1 != 0' | wc -l 0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1962359 Title: Hibernation fails due to resource busy during swap file check To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1962359/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
