Feb 29 20:06:45 shosta PDC202XX: Primary channel reset.
Feb 29 20:06:45 shosta ide2: reset: success

The ide2: reset is what is most likely causing the hard lockup, but I 
have no idea what to do to fix this.  I have tried multiple drives and 
different ribbon cables, and no luck.  Has anyone else seen this?
