Thanks for the input.  I can try removing some of the options and seeing if
it helps anything.  I believe the reason I specified version to was because
I'm using a Thecus N5200 RAID device which I think was only letting me mount
via version 2.  Auto is mounting at startup so I dont have to specifically
mount when I reboot.
