Description of problem:<br />
The most recent yum update caused it. I don't know which package. I have done a clean install that was functional (gnome desktop +devel), then a yum update that broke the system. <br />
<br />
Version-Release number of selected component:<br />
kernel<br />
<br />
Truncated backtrace:<br />
