Ouch! So even updating to the latest driver doesn't solve the link state=20 issue? I don't use jumbo frames, but it's critical that this server remain = in service 24/7, so I don't want to upgrade if there's no improvement in=20 that issue. Switching to the Intel card would be a bit of a PITA on a=20 remote, rack-mount server. :-( --=20 Paul Schmehl (pauls@utdallas.edu) Senior Information Security Analyst The University of Texas at Dallas http://www.utdallas.edu/ir/security/ --==========863A1BABDF4141065CAD==========--
