Hi All. I never posted the fix for TFTP open timeout.
navigate to /etc
then type in
sudo nano rc.local
then your password.
next, add this one line before the end:
/bin/sleep 30 && /etc/init.d/tftpd-hpa restart
hit ctrl + o
then ctrl + x to exit.
I can also confirm that HP 8100’s and 8200’s work with the latest kernel out of the box.
