Lancelot 2851 shuts down instead of rebooting

Problem:

Lancelot 2851 shuts down instead of rebooting

OS Versions:

  • Ubuntu 12.04.3
  • Fedora 19

Details:

When issuing the reboot command the system will power off instead of restarting. In addition, the system may hang upon boot with the following error message:

mei: Init HW failure

Solution:

Both issues are caused by loading of the mei.ko kernel module. According to the motherboard vendor, ME should not be reinitialized by the operating system. To prevent loading of the mei driver, create the following file:

/etc/modprobe.d/blacklist-mei.conf

With the following contents:

blacklist mei
blacklist mei_me
