Today I noticed for the first time that I'm getting the following messages in /var/log/messages on one of my F19 systems.
Jul 23 10:55:03 terrapin kernel: [ 122.662105] device p3p1 entered promiscuous mode
Jul 23 10:55:08 terrapin kernel: [ 127.669312] device p3p1 left promiscuous mode
These messages occur every 5 minutes and last 5 seconds.
I have 2 other F19 systems running on the same network that do not show these messages. The system that is seeing this problem is a Dell Inspiron
