dangerous situation with shutdown process

[Anatoliy Dmytriyev]

Hello, everybody!

I have found unusual and dangerous situation with shutdown process:
I did a copy of 200 GB data on the 870 GB partition (softupdates is 
enabled) by cp command.
It took a lot of time when I did umount for this partition exactly after 
cp, but procedure finished correctly.
In case, if I did “shutdown –h(r)”, also exactly after cp, the shutdown 
procedure waited for “sync” (umounting of the file system) but sync 
process was terminated by  timeout, and fsck checked and did correction 
of the file system after boot.

System 5.4-stable, RAM 4GB, processor P-IV 3GHz.

How can I fix it on my system?
