I have installed Fedora 17 on my laptop 3 days ago. Works flawlessly, but I always get this message on startup by automatic bug report tool on the left down corner. Detailed screenshot.

What does it mean, how can I resolve this?

I will only have to opportunity to update this stock Fedora in a few days though, as I'm now on mobile internet. But this says something about my BIOS... doesn't look like updates would solve this.

This is not a direct solution to the problem. but, if you do not want to display the message, you could change SELinux to permissive mode or disable it. Is not recommended because, SELinux is a Linux feature that provides the mechanism for supporting access control security policies.

How to change to permisive mode (recommended)


cp /etc/selinux/config /etc/selinux/config.bak

sudo gedit /etc/selinux/config

change SELINUX=enforcing for SELINUX=permisive

How to disable


cp /etc/selinux/config /etc/selinux/config.bak

sudo gedit /etc/selinux/config

change SELINUX=enforcing for SELINUX=disabled
