• Hi everyone,

    I have a brandnew Thinkpad x240 laptop (SSD included) and I want to deploy an image to it. I’m able to boot to Fog, but whatever task I choose from the menu (e.g. Quick host registration) the computer gets stuck and has to be turned off by pressing the power button.

    When I try to register, it gets stuck at:

    Error Unknown unclaimed register before writing to c5100
    Error Timed out waiting for DP idle patterns
    Error Unknown unclaimed register before writing to 64040

    I registered the laptop manually and tried to deploy and debug-deploy, but it gets stuck as well:

    acpi_walk_namespace failed

    I use FOG 0.32 with Kernel 3.8.8 on Ubuntu Server 10.04 LTS.

    I already tried Tom Elliott’s kernel, but that doesn’t work either. The laptop’s ethernet interface seems to be from “LCFC(HeFei) Electronics Technology”. The first numbers from the MAC are 28:d2:44. Maybe the correct drivers are not included in the kernels. Can anyone help? Maybe Tom?

    Thanks in advance!

  • Tom,
    I tried your bzImage from your Feb 11th post and it did not work on a Lenovo M93z that I have. I did download the bzImage from Chris and it does work. So it appears that something is still missing from yours. Thanks for your efforts in keeping FOG current!

  • Michael, not that you need to, but you can test my kernel as well. The issue you’re reporting seems more related to KMS (Kernel Mode Setting) rather than the issue that is plaguing the Lenovo’s. That’s not to say this kernel isn’t correcting the same issue you were seeing, but more just trying to get a kernel built that works across the board, as best as I can at least.

  • [quote=“Chris Sodey, post: 21062, member: 1418”]Tom,

    I will try to test your kernel. I finished making my custom kernel and it is working.


    I ran into this issue with some Dell 745 and 755 with ATI cards in them. This kernel worked for me as well. Thanks!

  • Magnus,

    While I appreciate the information, I’m not ultimately in charge the kernel’s you’ve listed here.

    I have built my own kernels which can be downloaded from:


    I don’t know if it will work, but I’ve modified mine to work from the KS tree as Chris has done. I don’t know if it will work, but as that’s really the only change from my original Core based kernel, and that’s what Chris used, it should work. I just don’t know.

    If you get a chance, please try it out and see. If it doesn’t use this kernel. I don’t know what other drivers he’s got added in though so it may not work across the board for your systems.

  • Chris,

    Another big thanks for your kernel. I was successfully able to get my clients (Lenovo Thinkcenter m83’s) to talk to the fog server and run an inventory and upload an image with your kernel. You saved me the pain of putting together a custom kernel myself or giving up on FOG all together.


    FYI I was unable to get either the kernel that was included with 0.32 or kernel v3.8.8 to load on my m83 client. Here’s the errors I observed with both:

    tps65010: no chip?

  • Chris,

    Thanks for the kernel. It worked great on a Lenovo X230 ThinkPad and a Lenovo M73 Mini Desktop.


    Thanks for all the work you put in on your kernels. I tried all of them. Unfortunately, I couldn’t get any of them to work with the Lenovos that I have.

  • Can someone please tell me what changed? Has any body had any luck with the latest kernel’s I’ve been producing?

  • Chris, you’re a lifesaver! We just got over 950 L440’s, and I’ve been trying different kernels with it all day till I finally tried your custom T440 kernel, which worked just fine.

  • Thanks Chris, kernel worked great! 🙂

  • Chris, thanks a lot for your kernel! it s working for me on a brand new x240

  • If you used kitchen sink I can get it and see the major differences. Just try my kernel and let me know if it works. If not I’ll compare the two configs.

  • I went back through my steps and the config I used was off of my FOG server. Location is /opt/fog-setup/fog_0.32/kernel/kitchensink.config. I copied that to the Fedora machine (/usr/src/linux-3.12.6/.config) Do you want kitchensink.config from my FOG server? I would bet you already have it.

  • Okay, so if I understand properly you used the fedora config?

  • Tom,
    I would post it, but I had Fedora 20 on the T440s and after I tested the T440p with my kernel and it worked I tested the T440s. I was so excited it was working that I didn’t backup the /usr/src/linux-3.12.6 directory before I wiped it with FOG.

  • Chris, can you post the config file. It should be located in the root of the Linux directory with filename .config (notice the period in front.)

  • I have tested my kernel with both the T440p and the T440s, both working. It is based off of Linux kernel version 3.12.6.

  • Tom,

    I will try to test your kernel. I finished making my custom kernel and it is working.


  • Okay,

    Chances are likely that that wasn’t the issue and you’re probably right about it not containing something. My guess is the Bus information isn’t translating properly, so I’m currently rebuilding the kernel to see if adding all possible South Bridges to the system, including PIIX4 (from Intel) will work. I’m not giving up, but I don’t know what else to try.

    I’ll hopefully have a kernel up for you to try shortly, if this works, I’m posting that configuration as my main config (TomElliott.config)
