How do you suggest me to do such log? It's hard to give because it's
rebooting one second after it crashes. If I'm not mistaking it's
crashing in a setup_cpu function (I don't remember the exact name).

Yes, with dom0 support.

By hand, I know how. With make-kpkg as well. But how do I do if I want
to create the exact same linux-image-2.6.26-1-xen-amd64 as you did,
using YOUR sources? I tried doing a dget on the .dsc, then doing
dpkg-buildpackage, but this didn't produce the expected package, plus
it's very long, as I saw it was building about 5 kernels (without
virtulalization, vserver, etc.) when I really only need the Xen one to
try to debug it...

One last thing I have in mind. My laptop comes with a e1000e ethernet
and 5300 wifi (both from Intel). Both of them only works on 2.6.27,
before it's either buggy or simply not working at all. Should I try to
create a patch against the current Debian kernel (kernel 2.6.26) so it
backports the drivers from 2.6.27, and it's included in Debian? I think
I could work on that if that helps having support for this hardware.

Thanks,

Thomas
