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.

PID %CPU %MEM TIME+ COMMAND
1575 25,3 0,3 3:04.39 polkitd
284 18,1 0,1 1:53.60 cgmanager

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.
