I’ve been having troubles since upgrading to Intrepid. Vuze (formerly Azureus) had a prob with 100% cpu usage and crashing. Found a neat command “sudo update-java-alternatives –set java-6-sun” that sets sun’s java as the default JRE, instead of GCJ. Now all is well in the world. 
We’re having a girl!
So I have this WRAP board that needed to be forced into using 10baseT on one of the NICs. Easy enough, just edit the config.xml file and add <media>10baseT/UTP</media> and <mediaopt>full-duplex</mediaopt>. Sounds simple right? Well for some reason those settings don’t work on WRAP based pfSense routers (I tried on 2 different boxes). After some digging, I just added <shellcmd>ifconfig sis1 media 10baseT/UTP mediaopt full-duplex</shellcmd> to the <system> area of my config.xml, did a few test reboots and everything looks good.
Yay!
