Version-Release number of selected component (if applicable):
kernel-desktop-2.6.38.8-10.mga-1-1.mga1

How reproducible:
always

Steps to Reproduce:
1. modprobe cx88_dvb

This message is a reminder that Mageia 1 is nearing its end of life. 
In approximately 25 days from now, Mageia will stop maintaining and issuing 
updates for Mageia 1. At that time this bug will be closed as WONTFIX (EOL) if it 
remains open with a Mageia 'version' of '1'.

Package Maintainer: If you wish for this bug to remain open because you plan to 
fix it in a currently maintained version, simply change the 'version' to a later 
Mageia version prior to Mageia 1's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that we may not 
be able to fix it before Mageia 1 is end of life.  If you would still like to see 
this bug fixed and are able to reproduce it against a later version of Mageia, 
you are encouraged to click on "Version" and change it against that version 
of Mageia.

Although we aim to fix as many bugs as possible during every release's lifetime, 
sometimes those efforts are overtaken by events. Often a more recent Mageia 
release includes newer upstream software that fixes bugs or makes them obsolete.

Mageia 1 changed to end-of-life (EOL) status on ''1st December''. Mageia 1 is no 
longer maintained, which means that it will not receive any further security or 
bug fix updates. As a result we are closing this bug. 

If you can reproduce this bug against a currently maintained version of Mageia 
please feel free to click on "Version" change it against that version of Mageia and reopen this bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
