Bug description
All was working fine for months, then suddenly (maybe after some update or after installing the low latency kernel or just by coincidence) the following problem showed up:
When using the "Suspend" function, in roughly 50% of all cases the system tries to suspend, but it doesn't work: The screen goes blank, but I can't hear the "click" from the power supply which indicates the successful suspend.
After approx. 40 or 50 seconds I will be returned to the desktop.
When looking at dmesg -T | tail -n 200, I can see the following two entries:
Freezing user space processes failed after 20.005 seconds (1 tasks refusing to freeze, wq_busy=0):
task:csd-housekeepin state:D stack:0 pid:2099 tgid:2099 ppid:1857 flags:0x00004006
And it is always the same task "csd-housekeeping" that prevents the suspend. (the strange thing is: it is called "csd_housekeepin" in the log, so a "g" is missing).
I found two people with the same problem, but no solution:

I noticed that after a fresh computer start it nearly always works, but the longer the computer is running, the more often I encounter the suspend problem.
In the meantime I restarted the computer a dozen times, but sooner or later the problem will show up.
Steps to reproduce
System button -> Power off the computer -> Suspend
(sometimes it works, sometimes it doesn't)
Expected behavior
The system should suspend in 100% of all cases
