[Bug 2078280] Re: System Crash on reboot/screen lockout: systemd-logind crashed with SIGABRT in __epoll_wait_nocancel()

[Daniel van Vugt]

Please:

1. Look in /var/crash for crash files and if found run:

    ubuntu-bug YOURFILE.crash

   Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.

Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.
