Can't say when the problems may have been introduced, but it looks like we've 
got my report (b104) and another report from b111 of issues with the 1068E.

The IR firmware seems to do some sort of internal multipathing while the IT 
firmware doesn't do any.  With the IT firmware, I enabled multipathing 
(in-between frequent reboots due to the card hanging under load) and had very 
good performance with the round-robin policy.

When I reverted to the IR firmware to fix my issues, I found that round-robin 
slowed down my disk benchmark tests (IOZone).  My guess is because it was 
trying to use pathways that the IR firmware had marked standby internally.  
Disabling the round-robin policy almost doubled throughput under the IR 
firmware.
