I did a clean install (keeping my old home partition) of ubuntu 12.04. Everything working fine, except the process avahi-daemon is consuming a lot (60-90%) CPU.

What is the avahi-daemon? Does it have something to do with Ubuntu One? I found guides on the internet on how to disable it, but I'm not eager to disable it, as it appearantly has use.

Hardware: Dell Studio 1557, intel i5, AMD Radeon HD5470

Avahi is a free Zero Configuration Networking (Zeroconf) implementation, including a system for multicast DNS/DNS-SD service discovery. It allows programs to publish and discover services and hosts running on a local network with no specific configuration. For example you can plug into a network and instantly find printers to print to, files to look at and people to talk to. It is licensed under the GNU Lesser General Public License (LGPL). (Source: Wikipedia: Avahi (software))

You could try to restart the daemon by following:

Open up a terminal(CtrlAltT) and type: sudo service avahi-daemon restart.

Hmm, so disabling it is a bad idea probably. It doesn't matter if I restart it or not. I'll probably best file a bug report for this. – Ruben May 3 '12 at 12:32
