I have seen this bug too (under Xen 4.2.0).

I am using the following workaround to stop those messages:

cat /sys/devices/system/xen_memory/xen_memory0/info/current_kb > \
        /sys/devices/system/xen_memory/xen_memory0/target_kb

I have not verified yet if Xen 4.2.1 is also affected.

Greets,
        Jacek
