Dear Ben Collins,

I'm not totally sure about the meaning of 'stock compile' kernel. If you give me
a hint, i'll try.

I don't know about the content of patches from libata 1.10 -> 1.11 in the ubuntu
kernel. But I guess that this might not the cause because the data corruption
happens with former libata version under different linux flavors (SuSE/Fedora).

Meanwhile the DMA suggestion sounds good to me cause I discover a new data
corruption problem under hoary while sending large files through a LAN (which
seems not to be present in breezy - but it's finally not tested so I will post
details later).

Thanks and bye,
Christian
