I also note that you are packing more structures here with this patch
than the code before the patch had. Could that be the issue here? The
additional structures are ones that should be packed instead?

If so, that might explain why things are working, just try to add the
packed attribute to the struct vmbus_channel and struct
vmbus_channel_debug_info and struct vmbus_channel_msginfo structures.

Although, if that solves the problem, then something else is seriously
wrong, as those structures should not being passed across the hypervisor
boundry...

thanks,
