 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.
