Bootlog bug?

Bootlog bug?

[Ron Madrid]

I have a little problem with my boot messages.  I'm not sure what this is, but does anyone have any ideas as to what it could be or what further information I could give to help track this down.  As of now this is not manifesting itself, but I don't know what it might do.

You have ended up with a duplicate device, or duplicate device _name_,
somehow.

This is the warn:

WARN(ret == -EEXIST, KERN_WARNING "sysfs: duplicate filename '%s' "
                       "can not be created\n", sd->s_name);

Turning on verbose bug info would show you the name.

cheers

Thank you.  I found my duplicate device!
