I'm also affected by this.
In particular, 5.2.9-2 and 5.3~rc5-1~exp2 showed this issue, I didn't
try 5.2.9-1.
Reverting to 5.2.0-2 everything works alright.

At least here, the same also happens with `shutdown -h now` and
`systemctl suspend`, it just stalls at the end of the shutdown/suspend
routine without actually shutting down and suspending the computer.
In my case, this is a Lenovo X1 Carbon 4th gen.

Here I have something similar, i.e. nothing interesting at all.  But I
don't see those ^@ (that I assume are some kind of file corruption, most
likely due to the file system not being cleaning umounted).

FTR, likewise I also get something like that as well, also for shutdown
(i.e. "Reached target Shutdown" for systemd, etc).
