 Besides, your problem seems to be different from the one I reported. I see
 the stalls even when using dd, and they're limited to the mentioned Vosoniq
 XS-drive; other devices like my iRiver player work fine (though a bit slow).
 However, until now I've only tried writing to the device which gave those
 stalls. Your mail gave me the idea that reading might be a different thing -
 I'll try that.
