I updated my machine over the weekend to FreeBSD X220.alogt.com 10.0-STABLE FreeBSD 10.0-STABLE #38 r267699: Sun Jun 22 16:32:07 WITA 2014 erich@X220.alogt.com:/usr/obj/usr/src/sys/X220 amd64 I started it only a single time with IPV6 enabled and the machine crashed again. It looked to me that it was the same location but I did not verify it. I run the machine since then with IPV4 only and did not have any trouble. Maybe a word to the timezone. It seems that we are 12h apart. So, early morning and early evening would be the best pairing for us.
