Ah, my motherboard is in fact an ICH5 I believe.
Incidentally my kernel is actually 2.4.23-pre4.
Generally the ICH5 support just works, but it may not be doing dma.
I've have some stability issues with some configs before I started
applying libata patches to my kernel. This was a long time ago. Also
ctcs pounds on things pretty hard.
Is there any documentation about what libata is and what it does differently
from the stock kernel?
Libata is just another driver patch for the linux kernel. It uses
the scsi subsystem instead of the ide subsystem. Jeff has pdf some
where, but as I remember it was geared for developers.
Why is it being developed separately instead of as a
set of new drivers in the kernel like normal?
