I've got only a similar, very stable, system running kernel 2.6.18-mm3. I will try out the last stable version from www.kernel.org (2.6.21.3) and give you further information. Bye Stefan ======Originalnachricht====== Von: "Parag Warudkar" <parag.warudkar@...il.com> Datum: 2007-05-28 00:45:38 An: "Stefan Helbing" <sth@...ltd.eu> Betreff: Re: Oops in kernel 2.6.21 [ It's NFS - CCing Trond ] Hi Stefan, What was the last kernel that worked for you without giving this problem? Also is it possible for you to try the latest kernel (http://kernel.org/) to see if the problem is still reproducible?
