>Description:
During shutdown the buffer sync SOMETIMES fails with
syncing disks, buffers remaining... 55 55 55 55 55 (some times more, don't know exactly)
giving up on 55 buffers

I am using UFS2 for root and UFS2+SU for all other filesystems (/var, /tmp, /usr, /home).

The same problem exists with 5.1 and 5.1-current.
>How-To-Repeat:
The problem appears irregular on shutdowns.
