Looks like the suspend message is received in the shutdown handler.  
schedule_work is called to schedule the work but, sporadically, that work is 
never executed.  It is as if schedule_work doesn't really schedule it or it is 
unable to get executed.

I decided to put in some printk's into reboot.c's __do_suspend.  During a 
"good" live migration run I see the printk's show up on the console.  In the 
bad one I see that __do_suspend never gets called :-(

I'll continue to follow it up the chain to see if it never gets the message to 
suspend at all or if something is going bad between getting the message and 

I'm running xen-2.0-testing with the xen-2.0 kernel BTW.
