To:
I install a squeeze system from a mirror which has not been
updated for few months. Then I add security repository info to
/etc/apt/sources.list and then run 'apt-get update && apt-get
dist-upgrade' and I think this upgrades the kernel, so that after
the dist-upgrade I have:

	fiori$ dpkg -l | grep linux-image
	ii  linux-image-2.6.32-5-amd64               2.6.32-34squeeze1             Linux 2.6.32 for 64-bit PCs
	fiori$

Buuuuut ... I do not reboot to activate the new kernel yet! This is
because this is all being run from a script which configures a system
as I want and installs lots of packages.

I then run m-a to build modules for iscsitarget-source (but I get
exactly the same behaviour for nvidia-kernel-source, which is why I
think this is a m-a bug, not a iscsitarget-source bug). The command
line I use is:

	m-a --kvers-list 2.6.32-5-amd64 --text-mode --quiet --non-inter auto-install iscsitarget

The result is this:

As you can see, there are no compile errors and the package .deb
has been created and it installs successfully and, after a reboot,
I can use it, without problems. It is simply that m-a is saying:

	Package iscsitarget-source was not built successfully, see /var/cache/modass/iscsitarget-source*buildlog* for details!

but this is not true! The log file
/var/cache/modass/iscsitarget-source*buildlog* contains exactly the
output which is displayed above. But here it is completely:

I believe, but am not 100% sure that this was not a problem when
squeeze was first released, because there was no kernel upgrade
available, but, now, several months later, there is a kernel upgrade
available, so I do it, and now m-a fails.

Further info: I did the same procedure (install from old mirror,
configure security updates, run apt-get update && apt-get dist-upgrade,
use m-a to build modules for a different kernel to the one that is
running) with lenny, but there was no problem there.

If you need more info (e.g. running some extra commands before and
after running m-a, running m-a with tons of debug enabled, etc),
then please let me know.
