I'm still able to build and boot here, so I haven't reproduced the
issue .. so I'm still hesitating to revert all the xencommons changes,
as I can't prove to myself they are the issue.
I created a kirkstone branch today, and I'll be adding the latest Xen
patches to it, but I need to get a handle on what everyone is seeing
for failures.
I assume you are still seeing problems with the boot on all the
platforms you mentioned above ?
