Hi Kevin, this sounds very familiar to a problem I asked about on this list a few days ago. http://www.mail-archive.com/als...@li.../msg28769.html Unfortunately I haven't heard of any solution. My temporary fix is a script that polls the power state of Node 0x1f and sets it back to D0 if it is in state D3. Daniel |
