| |
After upgrading to 2.6.0 (from 2.4.22)I'm getting a lot of the below messages in my logs. I'm well aware that this might purely be a problem with the binary Nvidia drivers I'm using with my Geforce3, especially since I had to use the patches available from http://www.minion.de/ to be able to use those drivers at all, but I thought I would report it anyway, in case the nvidia drivers are simply exposing a real kernel bug somewhere that can be fixed without available nvidia source.
