Hallo I have problem with a Linux kernel oops. It mostly appears when I download files using bittorrent or other large file. I have a phone modem based Internet access using Home Internet Solution (http://en.wikipedia.org/wiki/Home_internet_Solution). I use Debian testing, Linux vanilla version: 2.6.21-rc6 (however I noticed that problem since Linux ver. 2.6.15, doesn't matter if that was vanilla kernel or from Debian distro), Here my sys info:
