Just upgrades my NUC from Bionic to Focal and suspend went from
immediate (within a couple seconds) to taking a whole 30 seconds. While
suspend is happening, the machine is still usable, mouse moves,
applications respond, all the way until the machine actually goes to
sleep. I don't see anything strange in kern.log that would explain the
slowness:

There does look to be 30s between the last "Lockdown: systemd-logind:
hibernation is restricted; see man kernel_lockdown.7" and "PM: suspend
entry (s2idle)"
This is mostly a frustration, but could be a security issue for some if
they suspend the machine and walk away thinking it would be locked but
is usable for another 30s.
