Yesterday I experienced some troubles with my ubuntu installation. After reset, my system didn't start lightDM, all I saw was a black screen. I then logged in via ctrl + alt + F1 to terminal and saw I'm getting the following error:

mei_me 0000:00:03.0: reset: connect/disconnect timeout.

I then followed instructions found here. That kinda solved my problem, but I'm still getting errors. I had some problems with the mouse jumping around. I then changed my desktop manager to KDM. But I'm not sure if this solved the problem or just the reboot.. Anyway it seems to be working now, but i still get some errors, I don't know how to fix. Here are the final few lines of dmesg:

Does anyone have some idea, what is going on? Any help would be much appreciated! I have ubuntu 13.10 installed, fully updated (I think).

CPU: Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz
GPU: Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series]

By the way, I have kubuntu-desktop package installed.

  • Do you need those mei features? I would just blacklist the mei_me module.

  • What I know about it is that it is some kind of remote management function used by sysadmins. (It can also be a new attack vector for the PRISM program.) I turned it of on all of my machines which has this feature, because I will never need it.

    "sudo rmmod mei_me mei" unloads the driver and will stop the mei_me messages (from bugs.launchpad.net/ubuntu/+source/linux/+bug/1196155)

OK, so after checking what this module does I have decided to just disable it, since I will probably not need it anyway. The solution was to add blacklist mei_me at the end of /etc/modprobe.d/blacklist.conf file:

# Intel VPRO remote access technology driver
blacklist mei_me

    I came here searching to find out what mei_me does... it would be nice if you included the information.
