Hy Sebastian,

Yes... working.. i am using now on Debian.
Use my .config and make the changes as you need.

dcgs0058:~# dmesg |grep mega
megaraid cmm: 2.20.2.6 (Release Date: Mon Mar 7 00:01:03 EST 2005)
megaraid: 2.20.4.7 (Release Date: Mon Nov 14 12:27:22 EST 2005)

Hi Bruno,

thank you very much for your answer.

I don't have any experience with vanilla kernels under debian. I know that
debian does not patch their kernels a lot (compared to other distros), but a
few patches, that might be important, are also in debian kernels. For
example one, that allows APT to overwrite files that are currently in use.
So I don't know if your config would also work against the debian patched
kernel.

Another reason I would like to stick to debian stock kernels is because of
security updates (with everything I have to do outside APT, I'm a bit lazy
sometimes; I have to admit that to myself)

But don't get me wrong; I really appreciate your detailed post! Really nice
to see that it is possible at least with a vanilla kernel to get Xen and the
LSI adapter to work with each other. But I hope that that is also possible
with the debian patched kernel.


So my question is if somebody knows if there is a way so that I can get the
LSI adapter to work with the Debian Xen kernel.

Thank you in advance...
