https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236383 Eugene Grosbein <eugen@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |eugen@freebsd.org --- Comment #1 from Eugene Grosbein <eugen@freebsd.org> --- Created attachment 202920 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D202920&action= =3Dedit Add wlock for priv modification to ng_iface_shutdown() The problem seems to be in ng_iface_shutdown() that passes zero ifp to if_detach(). Leaving aside bad memory, the only case in which that can be possible is se= cond call to ng_iface_shutdown() after it nullified priv->ifp and before it dest= oyed the rest. Sergey, please apply attached patch and add options INVARIANTS to your kern= el, too. If it does not fix your problem, please post your kernel config file and mpd.conf. --=20 You are receiving this mail because: You are the assignee for the bug.=
