Well,
I need to complement a bit what I wrote.
I had seen a bug report with a patch from May 2008 (kern/123980) proposing to
create this new 'flag': hw.ata.ata_dma_limit and I had understood first that
it had been included into 7.1. Therefore the wording of my bug report...
I checked the source code and it turns out that the patch has never been
applied, so the option simply does not exist.
This leaves me with my present problem: warnings and errors ( WARNING -
READ_DMA UDMA ICRC error) caused by either a corrupted 80 pins cable or a
problem within the kernel.
Daniel
