Lenovo Thinkpad x240

[Tom Elliott]

Looking at it, it looks like it possibly is competing for the write cache. Since both are fine, it dukes it out. I’m also assuming any kernel you’ve tried, you’re getting the same problems, is this correct?

[Chris Sodey]

The 3.8.8 kernel also freezes at the same point in debug mode.

[Chris Sodey]

I just received in a Lenovo T440p and it is freezing at the same point as the T440s, however the T440p doesn’t have a SSD cache.

[Tom Elliott]

Then I don’t know where the problem is. It must be something in the RAM is blocking it. Maybe UEFI is enabled? Maybe disable UEFI and go full legacy if you can?

[Chris Sodey]

That is the first thing I did was go full legacy in the BIOS. Are there any models that have worked with FOG that have the 4th gen Intel mobile processor?

[Chris Sodey]

Another question would be, does FOG depend on the OS at all? I am running Ubuntu 12.04 LTS x64. Would it be better to choose a more current OS?

[Tom Elliott]

I don’t know. I’ve tried compiling any and all intel based information(s) that I could find, but so far nothing seems to be working. If I could narrow down the exact issue (as it isn’t spitting out any information to you) I might have better luck, but until then I haven’t got the foggiest (forgive the bad pun) idea of what to do.

[Tom Elliott]

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)

[Tom Elliott]

Kernel is posted as:

Tom,

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

[Chris Sodey]

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 Elliott]

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.)

[Chris Sodey]

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.

[Tom Elliott]

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

[Chris Sodey]

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.

[Tom Elliott]

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.

[giejo]

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

[marko]

Thanks Chris, kernel worked great!

[MCS IT Dept]

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.

[Tom Elliott]

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