I'm willing to perform some tests within the next 4 weeks when our server hardware (Dell PowerEdge 1950-III with two if_bge() NICs and 16GB RAM) changes OS from FreeBSD 8.0 to RedHat Linux. In a time-window of about a week I might be capable of testing FreeBSD 8.0 as it would be that time by the mid of November with a setup of Linux (distro doesn't matter as I can choose). I need to know WHAT, WHERE and HOW. Thanks. oh
