Is it possible this bug returned in ubuntu 21.04 - hirsute? see my systemd-shutdown in the txt file attached. ..or is a workaround possible for this?
I notice this behavior when i shutdown and reboot. the laptop needs almost no time to shutdown, and then for 20 maybe 30 seconds the plymouth screen comes back with the rotating sign, waiting to sync probably, then the screen goes black and shutdown. ** Attachment added: "last view lines of journalctl-shutdown" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1722481/+attachment/5504055/+files/journalctl-shutdown.txt -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1722481 Title: systemd should sync disks, before killing all processes on shutdown Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Xenial: Fix Released Bug description: [Impact] * systemd-shutdown binary is executed to complete system shutdown. In xenial, it calls sync() after killing all processes, and not before killing them. This means that processes are racing the SIGKILL/TERM timeouts to sync all IO to disk. To mitigate this race condition, and make the shutdown process more reliable the sync() should also happen before process killing spree starts. [Fix] Backport upstream commit https://github.com/systemd/systemd/commit/2e79d1828a8da9b3af1b052297e3617905ec94f3 [Test Case] * Make sure systems still shuts down, including e.g. root on raid. [Regression Potential] * Shutdowns may appear to be slower due to two sync() calls instead of one * However total shutdown time should not be impacted much, as there really should not be much additional IO caused by killing all processes.
