There's a few ways this can come about. Most often you emerge something that wants to write new configs that are config-protected and you don't accept the changes. First step is to find what causes the difgfrent behaviour and you need to take a logical step-by-step approach Compare the udev rules files on both machines in /lib/udev and /etc/udev and make the non-working host the samne as the working one. Do these two machines run the same arch and have similar services running? -- Alan McKinnon [email protected]
