does your way shut down/ reboot the 2010 fully ??
It is not the method that causes that ..... the incorrect shut down sequence is being called, which causes it.
I posted about that previously I think ....... but if when running live from a USB stick you delete the /etc/rc.d/init.d/halt
file, and rename the /etc/rc.d/init.d/halt.livecd
file to /etc/rc.d/init.d/halt
then the stick will shut down correctly.
I did not bother digging any deeper, reckoning that it would be corrected quite soon.
I thought it might have been corrected for the re-issued ISOs ...... but have not checked them.
