Badness in pci_find_subsys & sleeping function called from invalidcontext
From: Jesper Juhl
Date: Mon Dec 22 2003 - 14:16:52 EST
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.
