https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D253593 --- Comment #8 from Patrick Sullivan <sulli00777@gmail.com> --- spoke with Peter earlier and realized that the script I posted was way too heavy. This is enough to cause the panic here: mkdir -p /test/jail/mnt /test/mounted/subdir && cp /rescue/(sh|sleep) /test/jail && mount_nullfs /test/mounted /test/jail/mnt && chroot /test/ja= il /sh -c ' cd /mnt/subdir; /sleep 10; cd .' & sleep 1; mv /test/mounted/subdir /test/outside ; sleep 10; umount /test/jail/mnt ; rm -rf /test It's a one liner you can copy and paste in to repro the issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
