But for some reason noone else has it. It makes me think it's something with the configuration. But in fact it's a clean install of Fedora 7 with all the option set to its default values (except for the firewall and selinux which are disabled) and just ntp turned on... Can it be a problem with my hardware (I mean motherboard)? Is there a way to trace it? Thanks!
