Release Found: Red Hat Enterprise Linux 5.2

The Sun Netra ATCA CP3220 and CP3250 blades were originally certified on 64-bit (x86_64) Red Hat Enterprise Linux 5.2 using a special driver package for the Sun 10 Gigabit Ethernet device. That driver package is called a kmod package and it can be downloaded from this location:

Please note that although the link's Platform selection says Red Hat Enterprise Linux (i386), the package actually includes 32-bit (i386) and 64-bit (x86_64) drivers. This kmod package is only required for Red Hat Enteprise Linux 5.2 as the driver ships in Red Hat Enterprise Linux 5.3 and later.
