mdadm: failed to stop /dev/md1

I have just finished (finally!) installation of 2005.0, and I've noticed on
console-screen some strange message always, when doing shutdown:

mdamd: failed to stop /dev/md1 array, device or resource busy [!!]

/dev/md1 is mounted as root partition, apart from that I have
7 more /dev/md partitions, all are stopped without any message.

Right before "shutdown -h now" I tried to see if there are some
files open, but "lsof /dev/md1" showed nothing...

I can not find any other relevant messages, syslog-ng is stopped
before this error, and shutdown continues as usuall. Any ideas?

> have you tried doing the same to the partition the array was mounted on?
> # lsof /mount/partition

well, my /dev/md1 is root-partition, so I issued:

lsof / | less

It gives me a lot of opened files:
init
khelper
kacpid
kblock
kswap
md*_raid1
udevd
kjournald
syslog-ng
acpid
named
sshd
apache
cron
agetty
...

I think they should all be closed at shutdown...
Where should I put link to lsof so that it would display opened
files right before mdadm tries to stop arrays (when doing shutdown)?

I've got / on an md device and I recently started seeing this behavior also.
