They all show up when using "magic SysRq w". In htop they all have big fat red 'D' in the state column. Is this really desirable? I have attached the output of "ps aux" after boot and the SysRq-w output. -- Markus --Dxnq1zWXvFF0Q93v Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename=ps_aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 7.5 0.0 180 36 ?
