[Bug 1882505] Re: ubuntu_ltp_syscalls failed to run on Focal s390x, unable to restart systemd-timesyncd.service

[Po-Hsu Lin]

Looks like this has something to do with systemd,
with zVM boot with 5.4.0-33, I can still reproduce this issue:

ubuntu at kernel04:~$ sudo systemctl stop systemd-timesyncd
ubuntu at kernel04:~$ sudo systemctl start systemd-timesyncd
Failed to start systemd-timesyncd.service: Unit systemd-timesyncd.service is masked.
ubuntu at kernel04:~$

+ ubuntu_ltp_syscalls failed to run on Focal s390x, unable to restart systemd-timesyncd.service

Bug description:
  Issue found on 5.4.0-34.38 s390x LPAR / zVM

  We need to stop timesyncd for the following tests:
  ['leapsec01','stime01','settimeofday01','clock_settime01']

  But it looks like when we're trying to restart it:
     systemctl start systemd-timesyncd

  It will fail with:
    Failed to start systemd-timesyncd.service: Unit systemd-timesyncd.service is masked.

  
  This issue did not happen on 5.4.0-33.37, the ubuntu_ltp_syscalls test can finish with that kernel.
