If you find time, could you try the latest (or close to the latest) upstream version, following the instructions from here? http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-kernel-org-package (Short version: $ (umask 077 && mkdir workspace) $ cd workspace $ wget http://www.kernel.org/pub/linux/kernel/v2.6/testing/linux-2.6.39-rc3.tar.bz2 $ tar -xf linux-2.6.39-rc3.tar.bz2 $ cd linux-* $ make localmodconfig $ make deb-pkg $ cd .. # dpkg -i *.deb ) If that version fails, too, the best thing would be to bisect. It works like so: # apt-get install git $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git $ cd linux-2.6 $ git bisect start -- arch/s390 mm $ git bisect bad v2.6.39-rc3 $ git bisect good v2.6.32 $ make localmodconfig $ make deb-pkg ... try it out, and ... $ git bisect good; # if it has the null pointer dereference $ git bisect bad; # if it doesn't $ git bisect skip; # if some other problem makes it hard to test $ make deb-pkg ... repeat as many times as wanted ... This can help quite a lot, to figure out what change or family of changes introduced a bug. Thanks again and hope that helps.
