Thank you Pasi,
Will dig a bit deeper. I saw that page also has very detailed
instructions for a custom kernel, I will try and tune a little and
compile a few versions. I have a feeling it may very well be graphics
related. Will feed back here when I have details.
I have extensive C and hardware/embedded knowledge and would love to get
a bit more involved in Xen. Hopefully I can contribute, however small,
here and there :-)
Kind regards,
Andi
