I compiled a test kernel from the following Git today.

http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/powerpc-dma.4

Command: git clone git://git.infradead.org/users/hch/misc.git -b
powerpc-dma.4 a

Unfortunately I get some DMA error messages and the PASEMI ethernet doesn't
work anymore.

What kind of machine is this (and your other one)?  Can you send me
(or point me to) the .config files?

Hello Christoph,

Thanks for your reply and sorry for my bad email at the beginning. I 
have bad experiences with rewroting of good working code. Actually I 
work for the first level Linux support at A-EON Technology Ltd. Our 
customers are typically desktop users. That means, we don't have always 
time to hunt kernel bugs. Our customers are only interested in new 
features, stability etc. It is really difficult to explain them about 
rewroting of good working code as a new feature. For us as a first level 
support it is very difficult and time intensive to look why the new code 
doesn't work.

@All
Please also think of us because we have to explain your work to the end 
customer. And it is really hard for us and time intensive to prove 
mistakes because of rewroting code over and over again in opposite to you.
It is really a pity if you replace a good working code (The work from 
another developer with a lot of bug fixes) with a buggy code. 
Incidentally, it is also expensive. (time + money)

@Christoph
Anyway, back to testing. I tested your kernel on an A-EON AmigaOne X1000 
and on an A-EON AmigaOne X5000 today.
