Can you also see if: have you ever thought about that the real problem could be that fsck can not determine the fs type soon the partition is dirty? in my experience it does not matter if it is SU or SUJ, the problem is that fsck bails out and the system boots normally even with bad blocks, because of this fatality the errors are dragged from boot to boot and things are getting worse since I added -t ufs to /etc/rc.d/fsck I have no problems anymore with this issue background fsck of course must be disabled and fsck_yes enabled H > kern.cam.ada.write_cache=3D0 > hw.ata.wc=3D0 > > while leaving SUJ enabled helps at all? > >> On 8 March 2012 11:07, David Thiel <lx@freebsd.org> wrote: >>> On Mon, Mar 05, 2012 at 05:12:16PM -0500, Arnaud Lacombe wrote: >>>> I've been running a couple of system with 9.0-RELEASE since it is ou= t. >>>> All the system were installed through the standard installation >>>> procedure.
