Since upgrading from beta 25 to 6.9.0 (now 6.9.1) I have had my hp nc523sfp network card continually drop out. Initially it appeared there was no rhyme or reason but now its consistently doing it approximately 30 minutes after restarting my server. Card works fine in the mean time. Unfortunately it has rendered my server useless at its primary role. It appears that the card is timing out for some reason and is unable to be restarted. Any ideas?
