For evaluation purposes, we have tried to install v7 with up2dates on a system based on the Intel 5000V "Blackburn" chipset with two Xeon "Dempsey" processors (i.e. Intel Core2-based).
The install fails to detect the NIC's and generates a variety of errors thereafter. Upon investigation, we have determined that full kernel support did not appear for this chipset until 2.6.18.
Will v7 (final product or next beta) be based on 2.6.18? Alternatively, is there a 2.6.18 or 2.6.19-tree Astaro development kernel we could test?
