OK
The story is--we haven't patched the 2.4 kernel with anything that would
affect IDE, or with anything else for that matter. You were using a plain
vanilla compile for 2.4.
And a udma2 rated disk from a reputable manufacturer was showing an echo
bounce on a signal gating line.... and line errors.
The one thing I would ask of you before I report this to linux-ide.org is to
change the cable if you can. It might be signal noise from an overflexed
cable showing up in the new drivers. Please report if you are able to do
this.
