Looks like this problem has been reported, and 1 person has a work-around. Could someone make Korba's solution into a patch? From: Korba <korba at kor.ba> Date: Mon, 30 Nov 2009 19:52:45 +0100 I had the same problem. I changed the e1000_read_mac_addr_generic() function in /usr/src/sys/dev/e1000/e1000_nvm.c to the 7.2 version. It works for me.
