AHCI is better, yes. It shouldn't be relevant this this problem though.

That is rather curious. There's no sign of any libata error handling 
going on.. Maybe the drive is actually returning that error code in the 
ATAPI CDB, or at least we think it is?

You are sure that this drive still works with older kernels using 
drivers/ide, and that the hardware didn't break at some point, I assume?
