Yes, there was a firmware issue with the V7000s back then. But this has been fixed. I still have a v7000 directly connected to my test z13 as an outcome of that bug back then. But as I said, unless this is officially supported by all components you should better use a switch. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www2.marist.edu/htbin/wlvindex?LINUX-390
