Recently I build a dual processor system with Tyan motherboard. Loaded Redhat 7.2, everything works fine, until I shutdown the system. Linux shuts down all the way, but system is not powered off. At this point the power button does not work and to shut off the power I have to disconnect the cable. I am pretty sure I have connected hardware correctly. Any clues Motherboard: Tyan S2507 Tiger 230 CPU: Pentium III (1 GHZ) X 2 -- Usman S. Ansari -- Kernelnewbies: Help each other learn about the Linux kernel.
