>Description:
        With an up to date -current both systems (i386 and amd64) paniced 
        with "indiracct: missing indir" during the nightly fsck_ffs -x.
        Both systems were running a pkgsrc pbulk at the same time.
        The stack is in both cases:

>How-To-Repeat:

        May require a kernel with options DEBUG and/or DIAGNOSTIC
