 Hi,
 
 Even though PR 53624 has been closed, I'm still seeing dom0 hangs in
 my Xen test runs, and they seem to be happening around the time of
 domUs exiting, with domUs having two block devices backed by plain
 files just as in the original PR.
 
 For logs, see the items marked "Log (with timeout)" here:

 Anything I can do to help debug this?  Is there a way to break into
 DDB from a serial console shared with Xen?
