Hello there,

 

since the only board-related thread here is quite old I decided to start a new one.

Inspired being featured on LinusTechTips I wanted to give unRAID a shot since I have a little Project on my mind where I can have a NAS-solution and pfSense running on a single machine and unRAID would be a great solution for this but I can't get te machine going.

 

 

The Hardware is

 

- MSI 890FXA-GD70

- Phenom II X6 1100T

- 32GB OCZ Evo Leggera

- AMD HD6450 (for unRAID)

- NVidia GTX650 (for pfSense <- YES, it's Overkill but the only Card I have in spare atm)

 

In general unRAID boots up just fine even with having SVM activated. So far so good but the fun ends when I want to enable IOMMU aswell für Hardware passthrough.

 

Having it activated the system sometimes gets to the Point where it prompts:

 

AMD-Vi: Found IOMMU at 0000:00:00.2 cap 0x40

 

 

But mostly it hangs at the Point posting:

 

Freeing initrd Memory: 50100K (ffff88007cf13000 - fff80080000000)

 

Having looked in the internet it is stated that the combination board/CPU has IOMMU-capabilites.

 

 

Since I need IOMMU working for my Intel Pro/1000 PT Quad-card to be passed through I really hope you can help me out here.

 

 

Thanks in advance and greetings from Germany

I have the same board... with the same problem.

 

From what I found here, https://bbs.archlinux.org/viewtopic.php?id=163102, the solution is run BIOS v1.80.

 

I've not tried it though, I'm on v1.15... I used a different server to run my VMs on.

 

Good luck!

 

 

Good morning,

 

thank you for your quick help. I will try the BIOS-downgrade in the next days to find out if it works for me. Since I have a Phenom II it should give me no headache downgrading.

I'll keep you informed if it works. 

 

Edit:

 

I found the time before coming to work to downgrade the board to BIOS-Version 1.8 and fired it up with IOMMU enabled and it booted up just nicely so in the upcoming week I'll try to find some time to explore unRAID.

Thanks again for the tip and the link.
