Well, I just got mine and have started testing it with the LSI 9280-8e. So far it isn't working too well. It will recognize all the drives during boot (and takes forever to do so, mind you), but Windows cannot start the LSI card after booting if the SAS expander is attached. If I attach the SAS expander after Windows has booted and the LSI card has started, the LSI storage manager freezes (as will scanning for P&P devices in the device manager to see if the card died)...actually Windows seems to have died altogether now.
