I'm pretty certain I used mrsas_enable since that is what I would plan to use in production. I had a H330-mini with the same firmware rev in a R430. I was testing with some 2.5" Seagate ST9600205SS 600gb disks from another system. What kind of disks were you using and in what kind of configuration? Does a simpler config stay up? If you are using SSD, I wonder if disks would survive? SSD firmware issue? Was it hard hung at the console too? Can you enter DDB? If you don't mind, which Dell model is this? Sorry I don't have any directly helpful suggestions but you have good timing because this could very well influence hardware choices. Thanks.
