> Could you explain please where can I find all those bug reports, and > how exactly do I fix it? Hi, I am no geek. I asked the same question few days ago in this list and found out that this is for the computers with multicore processors. If yours is not dual core or something like that, then it is safe to disable it from the service manager. Previous discussion about this issue is here: https://www.redhat.com/archives/fedora-list/2007-November/msg04633.html Here is an interesting article about what it actually does (submitted by Greg Sieranski ) http://irqbalance.org/documentation.php Hope this helps
