Created attachment 523015 [details] [PATCH] hvcs: Ensure page aligned partner info buffer
I have no problems adding this patch, but if this is headed to be merged for 3.1 it will find its way into f16 naturally. How urgent is this?
Brian mentioned this is needed to debug anaconda. I'll add it to the kernel and it will be in the next build.
