Sorry for the wrong subject. The problem with the data abort is another one that happens after DHCP address reception. The kernel is from my today nigh build from head (FreeBSD 10.0-CURRENT r254955). This problem might be related to the recent mbuf changes. The PR link is http://www.freebsd.org/cgi/query-pr.cgi?pr=181602 This is the log from my console: Mounting local file systems:.
