Several of these, 32bit and 64bit HVM.  This is in the Citrix
Cambridge osstest instance.  The Xen Project colo instance is
unaffected (flight 101045 there passed with the same revisions of

This is with:

Sadly we haven't yet managed to make the logs from this instance

Do you have any idea what might be causing this ?  Is there a real
