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.
