Hi,

About the /dev/ devices...
I guess you upgrade by doing a make build?
It's nice if you would rebuild the /dev/ part of your system.

mkdir /nudev 
cd /usr/src/etc/etc.'uname -m'/MAKEDEV /nudev
cd /usr/src/etc/MAKEDEV.local /nudev 

shutdown to single user.

shutdown now or reboot with the -s option.

cd /nudev ; sh ./MAKEDEV all
cd /
mv dev odev
mv nudev dev
rm -rf odev

Note that be sure to have rebuild the dev's well, for else you wont
be able to reboot :)
Reboot after this and you'll have a new dev.
Bye,
