Comment 89 for bug 1810239

Hi,

I am having trouble passing through my Highpoint RocketRAID 640L PCIE Storage controller to a domU in my XenCenter home server.

It works fine on bare metal OSes, but seems to give behavior suspiciously similar to this bug, when I attempt to pass it through to a XenServer domU:

Server hardware: Asus Sabertooth 990FX motherboard with an AMD FX8350 8 core processor and 32GB RAM.

Could I fix this with this with the "dma-alias-v4" patch?
This does not seem to exist, as far as I can tell: git://github.com/awilliam/linux-vfio.git dma-alias-v4

Has this patch been committed to the kernel and is the reason I'm having problems that XenServer Uses 3.10?

Any help would be appreciated.
