Bug#786619: kfreebsd-10: EN-15:05.ufs: deadlock on reboot with SU+J



Package: src:kfreebsd-10
Version: 10.1~svn274115-5
Severity: important
Tags: upstream patch pending

Hi,

https://security.freebsd.org/advisories/FreeBSD-EN-15:05.ufs.asc
describes a bug I have seen affecting Debian GNU/kFreeBSD if
softupdates journalling (SU+J) was used on the root filesystem.

We didn't enable SU+J yet for the root filesystem, but we should,
or else single-partition (atomic) installs, which are the default
layout of partman-auto, will take a performance hit.  With this
fixed, enabling SU+J on root becomes an option.
