My machine has the following em(4) device and it has a autoneg problem. When I was using 8-stable kernel at 2010/11/01, it has no problem. But I update to 8-stable at 2010/12/01, the kernel is only linked up as 10M. em0@pci0:0:25:0: class=0x020000 card=0x13d510cf chip=0x104a8086 rev=0x02 hdr=0x00 vendor = 'Intel Corporation' device = '82566DM Gigabit Network Connection' class = network subclass = ethernet --- TAKAHASHI Yoshihiro
