Xen users - Jun 2010 - SLES11 Guest on SLES10 DomU. Call Trace upon boot of Xen Guest - Request to identify cause

Dear all,

    I just installed a SLES 11 guest.  I have noticed this call Trace
message when it reboots.  Did I miss some modules?
Call Trace:
 [<ffffffff8020c597>] show_trace_log_lvl+0x41/0x58
 [<ffffffff8046357f>] dump_stack+0x69/0x6f

 [<ffffffff8020bd19>] child_rip+0xa/0x11

---[ end trace af2fb56052b14f5e ]---

Shall summerize if emails are taken off list.
Best regards, S.
