Bug#850602: systemd: Suspending the system takes long (>10sec)

[Ralf Jung]

Package: systemd
Version: 232-8
Severity: normal

Dear Maintainer,

on my new laptop, suspending the machine takes pretty long (>10sec)
compared to what I got sued to on my old machine (<3sec).  I am not
sure where the cuplrit is.  Here's what the journal has to say for
these 10 seconds:
