- Does anyone have experience with patch 100584-02? Like many patches,
- it's difficult to determine from the description whether I need to
- install it. What might trigger this system freeze? How is the
- loopback interface involved? How would I recognize this type of freeze?
- Here's an excerpt from the README:
