>Description:
I've rebuild world+kernel this morning.

After installworld and mergemaster, I mounted another UFS2 partition
(a 6.3 install in the same disk) and removed a file, but after that I
was unable to umount it and I was forced do run fsck on the partition.

Tried again after reboot with the same result.

If I just mount then umount or create a file before unmounting all seems
ok, but if I delete a file on the mounted partition, the device is reported
as busy.

fstat doesn't report anything on the involved mountpoints.

I have these messages appear on  /var/log/messages

State-Changed-Why:  

Unfortunately your report does not contain much information to work on. 
Please send us the following information: 
mount 
dmesg 
sysctl vfs 
If this is consistent behaviour with only a specific filesystem, please 
provide additional output of: 
dumpfs (fsinquestion) 
disklabel (slice/deviceinquestion) 
Please try if this is still an issue with or without softupdates enabled and 
if it helps to sync;sync before umount'ing. 
If not, please send us your kernel config or at least a diff to GENERIC. 
Best is to try if you're able to reproduce this using a GENERIC kernel.

 Hello,
 
 I sent this directly to the list. For some reason the page I was looking at in 
 IE didn't have any links on it...my apologies if this gets posted to the list 
 again. I'm having I believe this same problem with 7.0-RELEASE on a new HP DL360 
 G5. Everything seems to work fine normally. I ran the system for a few days 
 doing all sorts of tests and there were no errors. Although, I just realized I 
 didn't test a read-only-on-boot fs (via fstab) in multi-user mode to see if it 
 happens there...I can try that on Monday.
 
 What follows is first a transcript of my single-user experience and then the 
 information "vwe" requested from the original submitter (which I don't see on 
 the query-pr web site). Hope it helps!

 A couple notes:
 
 * Interestingly, creating a file, THEN deleting a file, works just fine. It's 
 only if you first delete a file that it won't remount read-only.
 
 * A strange thing, once after hitting this problem I booted into (on accident) 
 multi-user, logged in to reboot, waited for 1 vnode and 2600+ buffers, rebooted 
 into single-user, hit enter for /bin/sh, fsck -y (no NO WRITE complaints), 
 mount, and / was mounted rw. I swear to Beastie, triple checked the scroll buffer.
 
 Now the requested info (disklabel, sysctl vfs, dmesg, dumpfs):

Subject: Re: kern/121809: unable to umount
Date: Mon, 9 Jun 2008 21:11:08 +0200

 FWIW, I'm experiencing the same problem when switching my /data filesystem
 from rw to ro.
 
 I have not included dumpfs output because it was 1.5 MB in size (600 GB
 filesystem).  Happy to send it on request.

 I'm also having this problem on 7.0-RELEASE.  My kernel is GENERIC minus stuff I 
 don't need, but with no additions.
 
 My nightly backup script does the following:
 
      mount -u -o rw /backup  (or just mount /backup)
      rm backup.prev
      dump -f backup.new ...
      mv backup.curr backup.prev
      mv backup.new backup.curr
      mount -u -o ro /backup
 
 The last step always fails.  The bug submitter says this happens when a file is 
 deleted, and that seems consistent with the behavior I'm getting.  I have not 
 tried turning off soft-updates.
 
 Let me know if you need more information.  Since I can reliably trigger the bug, 
 I would be happy to test a potential patch.
 
 Cheers,
 
 Eric

 I thought it was fixed, but today I'm seeing this again:
 
 # umount /mnt/data
 umount: unmount of /mnt/data failed: Device busy
 
 # dmesg | tail -3
 handle_workitem_remove: vget: got error 16 while accessing filesystem

 It's not really updated because I'm hoping for something about age(4) (At=
