Lubuntu 14.04:
The problem isn't always there. But sometimes I see policykit, cgmanager,
dbus-daemon, init, systemd-logind and NetworkManager eating up all CPU power.
The desktop is almost unusabe. The problem remains for a long time after system
start.

Title:
polkitd, dbus-daemon CPU usage high, system very slugish
Status in “policykit-1” package in Ubuntu:
Confirmed
Bug description:
After upgrading from 13.10 to 14.04, polkitd uses 60+% CPU and system
is VERY sluggish. Killing polkitd "fixes" the problem. This only
happens at boot. I've left the machine idle for 10 minutes, and still
polkitd and dbus-daemon are taking lots of CPU.
Sometimes NetworkManager as well takes a lot of CPU. Again, after
killing polkitd after boot-up, the problem goes away. polkitd gets
restarted and the system is responsive.
I didn't have this problem in 13.10 and previous releases.
