Re: PATA IDE is slower in newer versions of kernel

drivers/ide is pretty much obsolete - so what you are seeing is doubly
odd. Most stuff now is using the newer drivers/ata code which can support
SATA, NCQ etc unlike the old codebase.

One thing to check would be whether using the drivers/ata code shows the
same problem.
