Hi, I have been receiving messages on a new DomU''s kern.log. I''ve done a lot of googling, but haven''t came up with anything very useful, at least not in a Xen context. I was wondering if anyone had any suggestions about what could be wrong. From everything I have read, there should be a stack trace included, but I am not seeing one. Thanks in advance, Ian. on
