 Hi,
 I am using FreeBSD 5.2.1-RELEASE and have compiled my kernel with optinion:
 options   EXT2FS
 
 In my /etc/fstab I have added:
 /dev/ad0s6/mnt/debian ext2fs  rw  0   0
 
 to mount my debian box.
 
 everything works fine except one thing:
 Shutting down via shutdown -p now ends up in the message:
 
 syncing discs, buffer remaining 403938383838383838383
 .giving up on 38
 
 This means that FreeBSD is not able to umount/sync the mounted partition
 clearly.
 I have tried in /etc/fstab also the sync option but it ends up with the
 syncing discs giving up error message.
 Only if I umount the ext2fs partition gives me a clean shutdown.
 
 What can be done or how can I force the system to umount ext2fs partition
 before shutting down?

It's a known bug: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/56675

There's a workaround suggested in this thread, which you already seem to
know:

Ah ... I missed this one ... but good to know that it is a bug ... my first
step/workaround was to set the noauto option in fstab.
Now I have to find a way to bring the system to umount my ext2fs partition
(it is not only because of the syncing discs error but also my debian box
will run later on after rebooting the fsck check for about 10 minutes :-( ).
I was trying to bring the kernel automounter amd to mount the debian
partition but still did not succeed.
My second idea was to run a chron-job to umount my partition every 2 minutes
or so ... or set an alias on shutdown (with something like alias shutdown
umount /mnt/debian , shutdown -p now) ... I still do not know.

But thanx for your help and good advice (pointing me to the bug and the
page).

Oliver
