Hi all!
I second that. I can reproduce it on my i386 current machine (svn rev.
#216073) when running "make all" in ports/sysutils/coreutils.
(kgdb) list *0xc06821c9
0xc06821c9 is in free_jremref
(/jail/mytestjail/usr/src/sys/ufs/ffs/ffs_softdep.c:3578).
3573 static void
3574 free_jremref(jremref)
3575 struct jremref *jremref;
3576 {
3577
3578 if (jremref->jr_ref.if_jsegdep)
3579 free_jsegdep(jremref->jr_ref.if_jsegdep);
3580 if (jremref->jr_state & IOSTARTED)
3581 panic("free_jremref: IO still pending");
3582 WORKITEM_FREE(jremref, D_JREMREF);
(kgdb) p jremref
$1 = (struct jremref *) 0x0
(kgdb) up
#11 0xc068d1c6 in cancel_diradd (dap=0xc5fc0d40, dirrem=0xc5fd91c0,
jremref=0x0,
dotremref=0xc62045c0, dotdotremref=0x0)
at /jail/mytestjail/usr/src/sys/ufs/ffs/ffs_softdep.c:6783
6783 free_jremref(dotdotremref);
(kgdb) p dotdotremref
$2 = (struct jremref *) 0x0
Ciao,
Christian.
