BETA1 IPv6 crash
I installed BETA1 in a fresh ubuntu 11.04 KVM virtual machine with the new installer. Major issue I noticed was the missing /home. It took me quite some time to get IPv6 working in the guest (a Linux configuration issue), but now that it works BETA1 panics in about 50% of the boot attempts: testbsd dumped core - see /var/crash/vmcore.0 Sun Aug 7 08:25:28 CEST 2011 FreeBSD testbsd 9.0-BETA1 FreeBSD 9.0-BETA1 #0: Thu Jul 28 16:34:16 UTC 2011 r...@obrian.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386 panic: _mtx_lock_sleep: recursed on non-recursive mutex if_addr_mtx @ /usr/src/sys/netinet6/mld6.c:1676 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
