ATA Drive Issues

[Wil Hatfield]

Yah but I didn't see it as being "fixed" in 6.x either. That is why I
mentioned the lack of acknowledgement. If there wasn't a bug acknowledged
and tracked how can it be fixed?  Perhaps none of the Write_DMA problemed
folks have gone to 6.x and when they finally do the problem with show up
again. Who knows.  I guess maybe I am supposed to be that person.

Ok I am just nervous about going to 6.x and putting these customers through
this not once more, but twice when I have to go back to 4.x.

So far I have the Write_DMA problems and Fatal Traps that claim /dev/ad0 to
be the problem. Three outages today. Maybe it is time to look into the
penguin.

ATA on 6.x and CURRENT are being maintained by Soren, just not 5.x.
Moving to 6.x should fix the problem.  Checking gnats only shows
outstanding WRITE_DMA issues for 5.x.
