Bug#964926: systemd: systemctl show <service> prints "Failed to parse bus message: Invalid argument" before output

[Hugh Cole-Baker]

I just realised after doing some further testing that this report may
not be very useful, since the bug doesn't occur on the standard bullseye
linux-image-arm64 kernel - only on a kernel I compiled with customised
options. I will do some more debugging to provide more information on
the relation of this bug to the kernel options.
