I'm not disagreeing, but I've seen some very strange crap over the years come from those closed source video drivers so I do not trust them at all. If you can reproduce this without it loaded, please send the new oops message to the linux-usb mailing list and the developers there will be glad to work with you to track this down. Oh, can you also reproduce it with 2.6.24-rc3? thanks, greg k-h
