[119903.693261] BUG: unable to handle kernel NULL pointer dereference at 00000008

[Happy1789]

Before BUG event :
1/- installation of PAE enabled kernel under Ubuntu 10.04 Lucid :
sudo apt-get update
sudo apt-get install linux-headers-server linux-image-server linux-server
2/- upgrade of UBUNTU Lucid into UBUNTU Maverick
(upgrade done to solve crash issue of Videoporama 0.7.6 under Lucid to get Videoporama 0.8.0 under Maverick)
update-manager -d
3/- Videoporama and Firefox were working fine until I did :
a) an update of 58 packages,
b) and also a copy-paste into a terminal console this command line :
sudo lshw | less
4/- I experience also a reported bug (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/623140) with the other command line :
sudo lshw -C memory

Hi,
  We believe that this bug was fixed by a new kernel (2.6.35-21.30) released a couple of weeks ago. Please test that the

sudo lshw

command completes on your machine without an oops, and comment here either way.

Hi,
Indeed, it is solved two weeks ago after doing the following :
1/ reinstall Ubuntu Lucid Lynx
2/ install PAE enabled kernel
3/ upgrade into UBUNTU Maverick
4/ install videoporama 0.8.0
5/ process to video output as I wanted
6/ install the updates

Ubuntu Maverick 10.10
Kernel Linux 2.6.35-22-generic-pae

Thanks everybody for your help !
