Re: softupdate with journal panic

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)

6783                                            free_jremref(dotdotremref);
(kgdb) p dotdotremref
$2 = (struct jremref *) 0x0

Ciao,
Christian.
