  • Did you try adding the lineblacklist mei to the file /etc/modprobe.d/blacklist.conf? – Ron May 02 '15 at 15:58
  • No I don't try this, but I think this should work and causes in no errors at the bootup. But I don't know for what I need the mei_me service... Also this don't solve the problem, only the logs ;) – alabamajack May 02 '15 at 16:02
  • More about Intel mei. I've seen few people were able to solve the issue by blacklisting (or even doing rmmod) – Ron May 02 '15 at 16:13
  • Ron: Thanks for your help... I try to boot with an older kernel(xx0-49), and there the problem doesn't exist. My Problem now: How to tell grub to boot with the older kernel every bootup? – alabamajack May 03 '15 at 08:24
  • which kernal are you using? (the output of uname -a) – Ron May 03 '15 at 16:20
  • see the post;) the kernel it does not work : 3.13.0-51; the kernel it does work 3.13.0-49 – alabamajack May 04 '15 at 13:42
  • yeah, i meant the one which works :P – Ron May 04 '15 at 15:33

To tell grub to use older kernal everytime you can refer to the official documentation or this link. In short, you need to change the value of GRUB_DEFAULT in the file /etc/default/grub. To know what value you should put in for GRUB_DEFAULT, you have to refer to the order of boot entries listed in the grub menu. This information comes from the file /boot/grub/grub.cfg. This basically involves counting the menuentries and matching it with the position of your old-kernal as listed in the grub menu.
