Doing battle with a Dell R620 and Ubuntu

We recently got sent a Dell R620 to evaluate and while its technical specification is amazing there are a few things that need to be handled first.

As far as Ubuntu and the Dell R620 go, Precise (12.04) is the only way to go here. Every release before Precise has issues with this hardware in one way or another. This is new hardware of after all.

For our “use case” we downgraded the PERC H710P controller to a H310 controller so we can have direct access to the drives via pass-through. The H310 allows TRIM support for SSDs and SMART data via smartctl to be used without any problems. If you are interested in SMART information and PERC H700 series RAID controller, I posted about possible workarounds at Dell’s customer support site.

Ubuntu 12.04 (Precise) and AMD Catalyst 12.4

Precise Pangola has been released and a day later comes a new fglrx driver. While there isn’t a changelog, this build apparently gives us:

Among the bug-fixes for Catalyst 12.4 on Linux are: fixing some multi-head issues, a system hang in certain PowerXpress configurations, fixing a system hang when using OpenGL overlays, correcting an OpenGL performance drop, a soft-hang when killing the X Server, and severe corruption for OpenGL games using the AMD “Redwood” graphics processors.

If you want to build these for yourself then you can follow these instructions:

Wireless BCM4312 3.2 kernel

Broadcom Chipset BCM4312

Since there is an Ubuntu package ‘firmware-b43-lpphy-installer’ which is up to date and will work against the 3.0 kernel, my earlier posts are obsolete. If you are not running Ubuntu, then you will still need to reference my post.

The latest 3.2 Linux kernel however has a few ABI changes, most notably in the network stack which effects the Broadcom’s wl module. Most notably is: .ndo_set_multicast_list which was replaced with .ndo_set_rx_mode.
