Well, haven't yet been able to try the firmware suggestion, but we did replace the backplane. No change. I'm not sure the firmware change would do any good either. As it is now, as long as the SSD drives are attached directly to the LSI controller (no intermediary backplane), everything works fine -- no errors. As soon as the backplane is put in the equation -- and *only* for SSD devices used as ZIL, we begin seeing the timeout/retries. Seems like if it were a 1068E firmware issue we'd be seeing the issue whether or not the backplane is in place... but maybe I'm missing something.
