Comment 143 for bug 422536

If it were a BIOS bug, then it would have appeared even with earlier kernel versions. This bug appears when you run Karmic from RC on. Even if it seems that is not a bug itself, just an "oververbosing" of the notification system, it's pretty annoying and could prevent the early implementation of Karmic in a lot of systems with amd64 arch and nVidia video cards. I will wait until the next kernel update for installing Karmic on my main desktop.
