A fresh booted machine will begin dropping packets immediately. - We thought this was related to the upgrade from 11.3 to 11.4, and a fresh/clean install of OS 11.4 did not improve the situation - Kernel 2.6.37.6-0.7 did the same thing. Current Kernel level is : 3.0.4-2 Reproducible: Always Steps to Reproduce: 1. 2. 3. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
