I did comment on the bug reports and discussion and mailing list. I didn't
have time to do more, but was mostly ignored about this anyway, so i couldn't
do the indepth analysis i have done now. This is my most profund regret on
this issue though.

Because linuxppc upstream have hinted it is a considerable amount of work, and
nobody want to touch that code with a 10 foot pole, and i have more important
things to do both in debian and in RL. 

Why don't you do it if you think it is so important ? I didn't see you provide
any kind of code as far as i can remember anyway.

Whatever for ? It is not needed, and worse, there is no proof that it will not
just break existing hardware. Try building ide-generic and not pmac-ide on
your (power|i)book and see what happens.

Poking random x86-only registers on powermacs is nto a good idea, and see the
mention of kyle saying it may not even work on hppa, due to the bridges being
setup differently.

The rant is the stuff i added the first time, just keep the front note, and
the analysis immediately following it, but please remove all the stuff you
wrote which has been proven to be patently wrong now.

I can't believe that ! You prefer to keep your nonsense around, and obtusely
continue to claim there is a kernel bug while it has been proven that it is
not the case, oh well, and then people still wonder why things degenerated as
they did ...

The dependencies are not found in the source code, but are generated at built

Ok, what is the kernel bug, what evidence do you have that this bug exist
anywhere beyond your imagination ? you even couldn't be bothered to go over
the older bug reports and mailing list archives where the issue was first
mentioned, in order to show the bug. So, you should now take your maintainers
work seriously, and do a bit of research or shut up.

Notice that yaird became the default, and we started to get bug reports
rolling in only since 2.6.14, so how could what you say have been the case ?
2.6.13 was never uploaded, and 2.6.12 used initrd-tools.

If you think developper of embedded distros will use yaird over tools like
buildroot and co, you are severly deluded and have no idea about that milieu.

Furthermore, you are making a mountain about a imaginary bug, and are not even
able to go looking at the archives of back then and see what the real problem
was, but just bother other folk until they make the job for you out of sheer

Ok. So much for yaird then, this only leaves you giving up on yaird and
handling it to a maintainer who has a clue and is not interested in arguing
for the sake of it, or yaird being kicked out of etch because of

Well, you claim that you fail to understand yaird, you have said so repeteadly
either in erkelenz and in mail or irc these past days. I guess it is clear
that you are clueless, and don't want to take the effort to understand the
issue, relying on your upstream to fix bugs, but as your upstream went MIA,
you are lost.

by your own action and words, i believe that not only my judgement, but also
the one of most other debian developpers is far superior to yours, at least
when yaird and the kernels is concerned.
