Hello Christoph,
Thanks for your reply. I successfully compiled a kernel (uImage) for the
X5000 from your Git 'powerpc-dma.6-debug' (both patches) today.
It detects the SATA hard disk drive and boots without any problems. I
will test the first patch in next days.
Thanks for your help,
Christian

Interesting. This suggest it is related to the use of ZONE_DMA by
the FSL SOCs that your board uses. Let me investigate this a bit more.
As a hack to check that theory I've pushed a new commit to the
powerpc-dma.6-debug branch to use old powerpc GFP_DMA selection
with the new dma direct code:

And another one that drops the addressability checks that powerpc
never had:

Can you first test with both patches, and then just with the first
in case that worked?
