[Pkg-utopia-maintainers] Bug#987961: systemd-udevd using 100% of CPU

[Andrei POPESCU]

Control: reassign -1 upower

Hello,

Please note there is no systemd-udevd package.

The messages come from the kernel and upowerd so I'm tentatively 
reassigning to upower, hopefully the Maintainer(s) will have a better 
understanding of what's wrong / where this belongs.

Full quote below for their convenience.
