Xen users - Apr 2006 - Configuring a xen0 kernel - is the Wiki out-of-date ?

Hi list.

I am trying to build a new xen0 kernel to get the MEGARAID driver linked
in. I have done a "make world" and then gone into the
linux-2.6.11-xen0
directory (I know, I am setting up an old Xen 2.0.6, but I need to in
order to reproduce some odd behavior I have seen on my production server
which runs 2.0.6).

According to http://wiki.xensource.com/xenwiki/XenFaq section 5 you
should do 

  make ARCH=xen xconfig (or menuconfig of course)

instead of just

  make menuconfig

However, when I add the "ARCH=xen" bit I can''t see or select
any SCSI
low-level drivers. Doing just plain "make menuconfig" I can see them
all
(but then no Xen menu). Guess the Wiki is out-of-date or do I need some
other kind of incantation ?

Cheers

Hum, sorry, I do not have logs for compiling Xen 2.

I am using kernel 2.6.12 and xen 3.0.1-0tha5 on Debian. For what it''s
worth in Your situation, the logfile from my last sucessfull build of a
custom kernel shows that I did use

~   make-kpkg --append_to_version .6-xen-pdvibm14-dom0 --arch xen
- --initrd --config oldconfig configure
~   make-kpkg --append_to_version .6-xen-pdvibm14-dom0 --arch xen
- --initrd --config oldconfig kernel_image

after having unpacked the kernel source from kernel.org and applied the
xen patch to the kernel source.

This results in a
~   /usr/bin/make  EXTRAVERSION=.6-xen-pdvibm14-dom0  ARCH=xen vmlinuz

In this process I do see SCSI and low level drivers (using menuconfig).

I do btw. use
~   CONFIG_MEGARAID_NEWGEN=y
~   CONFIG_MEGARAID_MM=y
~   CONFIG_MEGARAID_MAILBOX=y
in my kernel.

On Dell 2850, stabillity is significantly improved by booting the kernel
using "noirqbalance nousb".
