[Bug 1896137] Re: syslog flooded with "Lockdown: systemd-logind: hibernation is restricted; see man kernel_lockdown.7"

[Gerald Gilbert-Thorple]

That's right, I masked them by hand following some advice on the internet for how to make systemd stop suspending, since it was not responding to settings in login.conf even after restating logind
service.

Regardless of my motivation, it seems buggy that changing these settings
should lead to such undesirable behavior.

Title:
  syslog flooded with "Lockdown: systemd-logind: hibernation is
  restricted; see man kernel_lockdown.7"

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  When I close the lid on my laptop, syslog goes crazy with the message

  systemd-logind: hibernation is restricted; see man kernel_lockdown.7

  repeated ad infinitum, using up all the CPU and GBs of disk space.  I
  am not even trying to hibernate; everything in /etc/systemd/login.conf
  is commented out.  So nothing much should happen when I close the lid,
  but systemd is trying to kill me with these messages.  I am running
  Ubuntu 20.04.
