2015-07-28 Thread Stephen Czetty 
I also see this error on 15.04, running 3.19.0-23-generic in a Xen DomU.

I had to patch the radeon driver in the kernel in order for it to work
correctly with passthrough.  I will take a closer look at that patch,
but it is pretty straightforward.

The relevant portion of Xorg.0.log:

I should have mentioned ... I'm now running with `3.19.0-20-generic` and
all seems well.

I was able to resolve this by updating my Linux kernel -- I had updated
from Ubuntu 14.04 through to 15.10, and needed to manually update the
kernel afterwards. (I believe the original kernel version was 3.16.0;
not sure which revision)

(The kernel was updated with a simple `sudo apt-get install linux-image-
generic linux-headers-generic`)
