I'm currently running Fedora 6 but have ran SUSE and UBUNTU as well and I seem to be having problems with all hanging. I'm running an IBM ThinkCenter P4 computer and I've got it on a KVM switch. I have no problems installing Fedora and running it, but if I leave it over night or for a period of time and then try and run a program the system will hang to a point where I have to turn it off and on again then it works fine until I leave it for a period of time again.....I've got all power saving features turned off, screensaver is off.....anyone have any suggestions??
