r720xd. h310 passthrough failure

Hey guys,

Thought I would come on here to ask this question.

Just got a new r720xd, and installed proxmox on it. I am trying to passthrough my h310 (it mode) raid card through to a freenas machine. I followed all steps in the documentation to passthrough my raid controller.

Everytime I start up the freenas vm the system crashes, I cant get into web interface, and my prompt on my monitor starts spitting out errors.

My prompt starts giving me the following type of errors:

"Buffer I/O error on dev dm-1, logical block xxxxxxx, lost async page write" and "I/O error while writing superblock. "

I have to restart the whole server in order to get the system to come back up.

Im new to this, so if i need to give you any terminal output let me know. Thanks in advance.
