I got the same kernel bug a few minutes after booting my system with 2.6.20-mm2. As a student i am not yet as familiar with kernel programming as i want to be, but i will try, i promise. In the meantime, i always try to test the newest mm patches, and i have to say, this one is the first which doesent work right on my sys since 2.6.15-mm1. Thanks, keep up the good work an please help me with this Problem Greetz Oli On 18/02/07, Andrew Morton wrote: > On Sun, 18 Feb 2007 18:58:05 +0100 Mattia Dongili wrote: > > > On Sun, Feb 18, 2007 at 02:06:59PM +0100, Laurent Riffard wrote: > > > Le 18.02.2007 06:51, Andrew Morton a écrit : > > > >Temporarily at > > > > > > > > http://userweb.kernel.org/~akpm/2.6.20-mm2/ > > > > > > > >Will appear later at > > > > > > > > ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.20/2.6.20-mm2/ > > > > > > Hello, I've got a fully reproducible Oops.
