One of the more promising solutions I'm looking at for my dual-ethernet dual-monitor workstation contains an Intel 82574L Ethernet controller. I found a LOT of postings regarding a bug in the driver for this controller: http://www.doxer.org/learn-linux/resolved-intel-e1000e-driver-bug-on-82574l-ethernet-controller-causing-network-blipping/ https://bugzilla.redhat.com/show_bug.cgi?id=632650 but there isn't any clear indication as to whether the bug has been resolved in mainline CentOS 6.4 or not. Has this bug been resolved? -G. -- Glenn Eychaner (geychaner at lco.cl) Telescope Systems Programmer, Las Campanas Observatory
