Yeah, data should be okay. All failed commands are retried.

That part of code got improved during 2.6.22 devel phase, so that's the
expected behavior. It seems that the promise controller has some
problems when connected to certain 3Gbps drives (IIRC newer Seagate
ones). It's most likely a hardware problem and we might need to default
to 1.5 Gbps on such combinations, but even without such modifications,
libata EH should do the right thing.
