Xen users - Sep 2008 - Windows SP, high CPU utilization xmtop after unpause

Hi,

I''m running xen-3.2.2-stable on a fedora-core8.

I paused my Windows-XP-HVM-DomU for about 2 hours. 

After this time, i unpause it, but I can''t ping it and the VNC does not
allow any mouse/keyboard input.

If I wait about 30 seconds after unpausing, all ping/vnc will work fine
again.
Within these 30 seconds, the xmtop shows 100% CPU utilization for this
DomU.

Could 
	a) somebody confirm this behaviour
	b) maybe help me to track down this problem ?

/var/log/xen/xend.log shows the "normal" pause/unpause log-entries,
Nothing special.

With a linux-HVM-DomU, there''s no such a problem.

One more info - if i pause the WinXp-DomU for only about 5 minutes, the 
ping/... works immediately after unpausing it... like it should work.
