ATA_DMA errors

This isn't a solution to my problem. I only have one hard drive.
It's 120GB Seagate. We seem to have different problems, btw.

I also don't think, my problem is ATA-related. It shows effect
on ATA, but I don't see any modifications that have been done
to ATA on -STABLE between May 26 and May 30. It is something else
going on there.

Today at night the system was up and the security scan showed
"bad descriptors" and "bad block"-errors. This was the effect
of my last experiment with latest -STABLE. (I previously thought
that the file system was intact, but it's not true.)

I don't know why this is called "bad block". It confuses users
(at least me) making them think they have physically destroyed
hard disk areas, but this is not the case, as a simple dd shows.
And bad blocks will not appear after using a new kernel and
disappear when I reinstall an older one and use fsck.
