Package: linux-2.6
Version: 2.6.32-5
Severity: important
--- Please enter the report below this line. ---
Sometimes when I connect a USB stick, I got a black screen or a blinking screen
a little like with a TV when the reception is bad.
When the screen is blinking, I found that I was still able to switch to virtual
terminal and here also the screen is blinking.
It is also still possible to reboot with the magic keys.
Here is what I found in /var/log/messages :

Or the computer case is not connected to the ground plane on the
motherboard. Anyway, this does explain the problem so I'm closing the
