CentOS - Mar 2012 - Intel igb driver question

Does anyone here know which CentOS release added support for 8086:1521,
 some I350 class device? We cannot get it to work under 5.4/igb driver
 version 1.3.16-k2. There must have been some major updates since,
 5.8 driver is 3.0.6-k2-2 and current is 3.3.6.

Does this help:


# rpm -qa kernel | sort
kernel-2.6.18-128.el5.x86_64

So it looks to me like support for that device was added to the igb 
driver in kernel-2.6.18-238.el5 (RHEL-5.6).

The 5.4 kernel is old and unsupported so you should upgrade.

Alternatively, try kmod-igb from elrepo which has the current release:

# yum list kmod-igb

Available Packages
kmod-igb.x86_64                    3.3.6-1.el5.elrepo 
   elrepo

I am not sure, but I was having a lot of problems with the stock driver in
6.2...I updated to the latest 3.3.6 and it all seems normal now.
