Hello,

there is some strange thing that happened after I installed Kernel 3.13.5 on Ubuntu 13.10.

After restart I selected new installed Kernel in GRUB. After that Ubuntu starts up like usually and I can see the desktop of Ubuntu.

But after some seconds (4 or 5) the computer restarts again by itself. And then it is always starting up until I see desktop and it restarts again, ...., ...., .... .

Only chance I have is to open GRUB during startup and to select my previous used Kernel Version 3.11.x.

Does anybody have an idea what can be a reason for this?

Thanks in advance!
