I am running the latest code which I compiled from RELENG_9_1, although I
can see that RELENG_9 is pretty much identical at this point too. I'm using
the amd64 architecture on an Intel Atom D525 motherboard. I'm using UFS2
with softupdates and softupdates journalling enabled. And it's mounted via
glabel. It works fine except when I try and reboot or shutdown the machine
I get this error:
Syncing disks, vnodes remaining...7 7 2 0 0 done
All buffers synced.
fsync: giving up on dirty

Then when the box comes back up again it detects that / was not unmounted
cleanly and recovers from journal before marking it clean once more.
My fstab:

/dev/label/swap none swap sw 0 0

I have also tried changing this to /dev/ada0p2 in case it was an issue with
using labels and it does the same thing. I had no problems with it
unmounting from the USB install stick that I used which was 9.1-BETA1, it's
only started doing this since I updated it to RELENG_9_1. I did make a
custom kernel file when I did that as well, but I don't think I've taken
anything important out of it. Any ideas?
Regards, Matt.
