Hi, all. I''m trying to track down some stability issues with my Xen
system, and in the course of doing so, I''ve found a few things that are
probably unrelated, but things I''d like to clean up nonetheless.
I have a Xen guest instance running my Xen0 kernel. When it boots I get:

I''m guessing this is saying that the kernel tried to take over the
frame
buffer device, but either it doesn''t have one, since no video cards are
allocated to this system, or its somehow going after a device that the
Dom0 has already taken over and is failing. Can anyone point me in the
direction of solving this?
Thanks!
