I did some similar testing in late Jan but perhaps not long enough to
notice your symptoms. 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.
