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
