Hi Clemens!

I am not very experienced on all the stuff around PATA and SATA but in 
my opinion there is difference between your case (you have an explicit 
error: "DMA timeout error") and my situation.

The problem for me is the messge: "ata : called with no error (51)!" 
This means not more than libata-scsi was not able to translate the error 
message from an ATA error to a scsi error. (that is only my point of 
view...  again I am not experienced on this topic) So it is very 
difficult to me to investigate the reason for the error. I would guess 
that your error really means some kind of problem with the dma modes of 
your hdds. In my case this shouldn't be a problem because the 3 disks 
are fully identical.

I am still searching for a solution, that's the reason for ataching your 
message and posting it to the kernel mailing list. I am still hoping for 
an advice to solve this issue.

Best regards and thank you for your interest,

Michael
