I saw this on ATAold as well, using cdparanoia, dd, dagrab, etc. I just
chalked it up to my drive being stupid, though it did it on several audio
discs. So, maybe it isn't me after all? I don't recall seeing any timeout
messages, though.

And when I say ATAold, I mean ATAold from a week or so before the ATAng
commit.
