ATA problems with FreeBSD 5.4

[Jim Campbell]

Jonny,

When I started using FreeBSD a month or so ago I experienced the same 
problem.  The only workable solution
for me was to use 4.11.  I corresponded with Søren Schmidt about this, 
but he could find no reason for this
occurrence.

If anyone can suggest a test for me to run to gather data for this I 
would be more than happy to do so.
