</span>That's your problem, 2.6.32 is _very_ old and obsolete. No one in the<br>
community can help you out with that release anymore, sorry.<br>
<br>
Please go get support from the company that is forcing you to stay at<br>
such an old kernel version, as you are already paying them for that<br>
support.<br>
<br>
I strongly recommend you use a more modern kernel release, you will find<br>
that things should be _much_ better...<br>
<br>
good luck!<br>
