You've put myself (I wrote GPLPV) and George Dunlap (from Citrix) in the
CC list but you don't say if you are using GPLPV drivers or Citrix PV
drivers. If you are using GPLPV drivers let me know and I'll get some
more information about the problem from you. If you aren't using GPLPV
drivers then I don't think I can be of much assistance...
