Well, Bret Ford reported the following inquiry info: SEAGATE ST410800N 7110 Martin Renters hasn't yet sent me dmesg information. What firmware revision do you have? The symptoms are that the drive just kinda locks up after heavy I/O. We hit it with a BDR after a minute and it comes back. > In fact without tagged quueing they have very slow performance. I'm sure they do. If we can track it down to a specific firmware revision, we can narrow the quirk entry a little more.
