http://ubuntuforums.org – Hi all, I've got a serious problem with Ubuntu 11.10 running on a DELL Optiplex 990 Machine. Whatever I do, the system randomly stops. Imagine you are working on a shell and randomly you won't get a prompt. Or while typing the system stops and won't return to the prompt even if CTRL+C'ed. I got the Hardware tested. Everythings fine. Memory, System (BIOS and so on, DELL has a pre-check-tool), Harddisk (smartctl health tests pass and so on) , Network (fine!) ... And the problems remains even if I have no GUI and pure shell. The System Clock seems to stop randomly, but kernelparameters like n (Hardware)
