Hi, List. Since I updated kernel by using yum, tux could not run. Kernel version is 2.6.8-1.521. The error message that yum outputs is "TUX not implemented in this kernel". It might be option switch for tux is turned off when new kernel is complied. Now I use old kernel of version "2.6.5-1.358" for lack of an alternative. Does somebody have any solution to avoid this problem? -- enchan <enchan@xxxxxxxxxxxxx>
