>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
