Comment 9 for bug 174211

NoOp,

How did you determine that your problem is the same as this one? This bug refers to smbd hanging on startup; do you have an strace of smbd showing this symptom on your system?

A browsing problem that's fixed by resetting the lo interface does not sound like the same bug; in particular, nmbd, the daemon responsible for advertising browse lists, does not talk to CUPS.
