Jeff,
Could we get this merged ASAP (it was first posted on 26th February)?
This patch fixes data corruption for libata PATA ServerWorks and HPT drivers.
[ IDE users are already leaving happy life since they are not affected
(modes masking has always worked correctly in the original drivers)...
Can we make life happy also for libata PATA users? :) ]
