Sounds good, turns out the issue was not with the MSFT initiator anyway. Thanks!

I see now that the benchmark causes the server to hang with "dpc_watchdog_violation" when testing against this iSCSI initiator. This does not happen against drives connect with MSFT initiator.

I just installed StarWind initiator because MSFT was very slow against my NAS. StarWind is much faster, but hangs my entire server half way though the benchmark. I have to hard reset my power to get the server back up.
