The ata driver is quite strict on standards implementation. It could be that 
the promise cables may not comply as strictly with the standard as it would 
prefer. Try getting 80-conductor cables from a third party. Generally 
speaking, buying your own cables is better than using the ones that came 
with the controller anyway, as those are usually el-cheapos, even with the 
most expensive controllers.
