I have had the joy of installing my medium sized FreePBX install. One if the challenges we faced was installing a second network card. This opened a very large can of worms. Basically the NIC keeped swapping orders and just in general causing all kinds of grief (even when we tried to use the MAC of the NIC to try and lock the Eth0 or Eth1.
What we ended up doing is bringing in a highly experienced Linux professional. He logged into the server and issued a uname -a to get the Linux version. He was very surprised to see for a new distro how old the Linux kernel was that we were using.
He also made comment that (2.6.18) which is the kernel version we are using has problems with multiple NIC’s and especially if they are of the GB type.
I have been doing some of my own research and I can see from the archives that 2.6.18 was released in 2006. The current stable version seems to be 2.6.39.
My question is can we safely update the Kernel without breaking FreePBX?
