I've been stressing Xen all week, and found plenty of bugs but not this 
one.  Can I ask a few questions about your set-up?

  - Is this dmesg in the dom0 or the domU (guest)?

  - You seem to have an x86-64 SMP kernel.  Can you provide details of 
the machine (how many cores, how much RAM, etc.)

  - How many guests are you running, and of what sort.  eg. What is the 
guest OS?  Is it paravirt or full-virt?

Rich.
