[gentoo-user] udev not getting unmounted at shutdown/reboot

[gentoo-user] udev not getting unmounted at shutdown/reboot

Hello, 
 
A few days ago my system hung and I had to do a reboot by pressing the power 
button. Since then I get the following message while shutdown/reboots 
 
Remounting remaining filesystems readonly [!!] 
umount : udev busy - remounted read-only 
umount : /: device is busy 
umount : /: device is busy 
umount : /: device is busy 
Give root password for maintenance 
(or type Control-D to continue):

If I don't do anything then the system reboots in approximately 5 seconds but 
on reboot it says that "/" filesystem is NOT clean. I boot into Slackware (my 
alternate distro) and during boot it replays over 100 transactions on Gentoo 
partition. It is a kind of routine. I shutdown/reboot, get the above 
mentioned message and then a "filesystem is NOT clean" on next boot. How can 
I get rid of this annoyance? Can this error harm my install any way?

Versions I am currently using
sys-fs/udev-070-r1
sys-kernel/gentoo-sources-2.6.14-r2

I have tried re-emerging udev but it did not help. 
Googling did not bring any results either. 
 
Any ideas to solved this problem will be highly appreciated. 
 
Regards, 
Abhay

Try doing an "init 1", "umount -a", then "lsof /dev".  Any processes
with a device node still open should show up there.

That did it. One of the programs I am starting in local.start was getting 
hanged at shutdown/reboot and didn't allow umounting of /dev. killall 
<program> in local.stop worked.
Thanks a lot.
