[Xen-ia64-devel] Xen/IPF Unstable CS#18286, dom0 CS#633 StatusReport --- some call trace in dom0

["Zhang, Jingke" <jingke.zhang@xxxxxxxxx>]

Hi all,
    All the test cases can pass with Cset#18286. When I check the 'dmesg', I 
found the unknown hypercalls was gone.
    But I met many call trace (39 times) printed out. My dom0 source is 
Cset#633.
