Hi I've filed a PR http://www.freebsd.org/cgi/query-pr.cgi?pr=35138 The story is short, after 4.5-RC update to Feb 6 -stable kernel crashes about once for two days or so. It's Ipv6 enabled irc server, lightly loaded, no special tuning. Unfortunately don't have debug kernel as -stable has been too nice for me for a long time.. hw.dc_quick: 1 GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.
