Lenovo Thinkpad x240
-
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?
-
The 3.8.8 kernel also freezes at the same point in debug mode.
-
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.
-
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?
-
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?
-
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?
-
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.
-
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)
-
Kernel is posted as:
-
Tom,
I will try to test your kernel. I finished making my custom kernel and it is working.
-
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.
-
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.)
-
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. -
Okay, so if I understand properly you used the fedora config?
-
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.
-
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.
-
Chris, thanks a lot for your kernel! it s working for me on a brand new x240
-
Thanks Chris, kernel worked great!
-
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.
-
Can someone please tell me what changed? Has any body had any luck with the latest kernel’s I’ve been producing?
