The same crash happens since v3.19-rc1 and still does happen= with v3.19-rc7. A bare metal boot is having no issues and also an Opteron base= d host is having no issues (dom0 and bare metal). Could be a table that the other host does not have and since its only hap= pening in dom0 maybe some cpu capability that needs to be passed on?
