Kernel panics when switching wireless networks — XPS 13 developer edition 9343

September 1, 2015

In addition to the recent fixes I posted for the XPS 13 developer edition, here is one more from the team.


Broadcom bug

Some customers may experience an issue where their system crashes when switching wireless networks while running the factory install of Ubuntu 14.04. The issue appears to be a bug within the Broadcom wireless driver. You can follow the bug report at the following link:

The current recommended fix is to add the PPA at the following link to your repository list and then update your system to apply the fix:

There are two methods to apply the patch detailed below:

Method 1

Run the following command to add the repositories using your package manager:

sudo add-apt-repository ppa:inaddy/lp1415880

Method 2

You can also add the repositories to your /etc/apt/sources.list file manually. Just add the following lines to the end of the sources.list file as in the screenshot below (requires root access).

deb trusty main

deb-src trusty main

After the repositories are added then update your system by running the following command:

sudo apt-get update && sudo apt-get upgrade

Here is my penultimate interview from ContainerCon.  Today’s video features Arjan van de Ven of Intel, the lead for The Clear Linux Project.   Clear Linux is Intel’s uber light weight OS and is targeted at cloud use cases.

Take a listen as Arjan takes us through the project.

Some of the ground Arjan covers:

  • Clear Linux as a modular micro distro that demonstrates how Intel’s hardware can be used.
  • How Clear Linux supports both containers and VMs

Recent Fixes for XPS 13 developer edition

August 28, 2015

About a month ago we stopped new sales of the XPS 13 developer edition in order to address a few issues.  A couple weSputnikScientist2eks ago we started selling the systems again.

For your reference, here are the details around the fixes:

  1. Keyboard repeat:  The unwanted keyboard repeat issue is being addressed via BIOS updates. The A05 BIOS update had some improvements however the as of yet unreleased A06 version will have the final fix in place. Keep an eye on the Dell support page at the below link to see when BIOS revision A06 is released.
  1. Suspend resume and trackpad cursor freezing:  The suspend resume issue and trackpad cursor freezing issue have been rolled up into “over the air” updates from Canonical. We previously had patches that were available through Dell Knowledgebase articles but will no longer be necessary. Going forward you only need to ensure your OS is fully updated to have these fixes in place.
  1. Out of box crashing:  The out of box experience crashing issue has been fixed through a change to the Ubuntu image put on the systems at the factory. All future systems shipped will no longer have this issue from the factory.
  1. DisplayLink driver available:  There is now a DisplayLink driver available to make the XPS 13 and M3800 developer editions compatible with our D3000 and D3100 USB 3.0 docking stations as well as the DA100 external video adapter. You can download the driver at the below link.
  1. Kernel panics when switching wireless networks: there is a bug report filed for this and Canonical and Broadcom are both working on this. Canonical released a PPA, just go to the following link and add it to your repositories and then you can get the patch after running your normal updates.
  1. Wireless channels 12 and 13:  Some customers in Europe might see an issue where they are unable to connect to wireless channels 12 and 13. If you are experiencing this issue call into Dell support to get help with this issue.

Thanks all for your patience and support!

ContainerCon: How Google helps developers with Kubernetes

August 26, 2015

Last week at Container/LinuxCon I conducted  a handful of video interviews.  Video number three stars Brian Dorsey from Google. Brian works with developers to get them up to speed with Kubernetes.

Here’s what Brian had to say:

Some of the ground Brian covers

  • Brian’s focus on cloud-building developers, specifically those working on Kubernetes
  • Key partners such as Red Hat, CoreOS, Kismatic and many, many more
  • How Brian and the team reach developers  (events, blogs, videos, sample code…)
  • Where he sees Kubernetes going over the next year

My new gig — I’ve joined the CTO office!

August 25, 2015

A couple of weeks ago I took a new position here within Dell.  I’m now in

Source: Schlomo Schapiro, OpenTechSummit 2015

the office of the CTO in our enterprise solutions group.  In  my new role the main areas I will be focusing on are DevOps and OpenSource.  And, because you can’t swing a dead cat without hearing about “containers,” I will be looking into that as well.  (I will also continue to drive Project Sputnik, the XPS 13 and M3800 developer editions)

While Dell has a bunch of activities in the above areas, they tend to be scattered across the company and we could do a better job of connecting them.  This will be one of my internally focused tasks, helping to get these efforts more aligned in order to better help our customers.

Externally I will be talking with customers, vendors and partners to see how we can go about creating viable and valuable POCs that will hopefully lead to bigger solutions.  Just like we did with project Sputnik, the idea will be to be transparent about these efforts and to start small and iterate.  With the goal of applying lean/agile principles our approach will be to put together quick, basic POCs that we can make available for customers to access and give input on.  The goal will be to draw on continuous feedback and course correct as we go.

That’s the plan at least.  Watch this space to see how it all unfolds :)

ContainerCon: Rancher Lab’s founder Sheng Liang

August 19, 2015

Rancher Labs
 debuted late last year and it has already made quite a splash.  Rancher positions itself as a complete infrastructure platform for running Docker in production or, putting it another way, it provides infrastructure services reimagined for containers.

Sheng Liang, who previously founded and then sold it to Citrix, is one of the founders of Rancher Labs and  their CEO.  I pulled Sheng away from the booth here at ContainerCon and asked him about his latest venture.

Some of the ground Sheng covers

  • What is Rancher labs and its main offerings: RancherOS (an uber light OS) and Rancher (a management platform for hosts and containers running on those hosts)
  • Where Sheng got the idea for Rancher labs
  • How they have taken in customer feedback and innovated to create offerings that hadn’t originally thought of e.g. RancherOS

Talking to Ubuntu’s Mark Shuttleworth re: Containers, IoT, Project Sputnik and Cloud

August 18, 2015

Yesterday at ContainerCon here in Seattle I ran into Mark Shuttleworth,  founder of Canonical and the man behind Ubuntu.  I asked Mark about some of the efforts Canonical has been focusing on recently and this is what he had to say:

This is what Mark had to say:

Some of the ground Mark covers:

  • Ubuntu on the mainframe
  • LXC (client) and LXD (on servers) which creates, migrates and kills containers
  • The recent Microsoft announcement that REST APIs from LXD will be implemented on windows
  • Canonical’s IoT work which leverages their efforts in the mobile area.
  • How Ubuntu Snappy works, why they built it and where are all the places its being used including drones
  • Their OpenStack work including connecting LXD w/openstack and using containers instead of VMs.  Also how to make much larger openstack clouds and build the ecosystem.
  • Props for the 4th Generation of Project Sputnik, the XPS 13 developer edition laptop
