Does it end up in an -sc- state? or a -b- state according to xl list?

I have had something similar on seemed to be just certain kernels. I had this 
most recently trying to install Ubuntu 12.04 on PV (12.10 seemed fine.) What I 
discovered was that I was using my own personal list of prerequisites for Xen. 
Looking back at the wiki, my private list was quite outdated and I was by now 
missing quite a bit of stuff, so I installed what I was missing, recompiled, 
etc., and the problem went away.


Hope this helps.
