Dear Kernel-Team,
I need to report a malfuction of pcieport or others,

cosmichaos@...michaos-desktop:~$ sudo gzip /lib/modules/2.6.32-16-preempt/updates/dkms/nvidia-current.ko
cosmichaos@...michaos-desktop:~$ reboot
...
cosmichaos@...michaos-desktop:~$ dmesg | grep -i taint
cosmichaos@...michaos-desktop:~$ sudo lspci -s 02:00.0 -vv
[sudo] password for cosmichaos:
