Success: successfull update and boot with new kernel (please see below for the details) Respect the instruction presents on: https://parisc.wiki.kernel.org/index.php/Debian_Ports_Installation I have only few observations: - the "/etc/apt/sources.list" must contains ONLY one repository reference, yours: deb http://ftp.debian-ports.org/debian unstable main - after the "apt-get install debian-ports-archive-keyring" and the "apt-get update" I was obliged to run - "apt-get dist-upgrade" because the simple "apt-get upgrade" was not sufficient. For the newbie: login as normal user, then switch to "root" using the "su" command. Thanks a lot for your very helpful support. I will start to put the details of this voyage on a wiki page as soon as possible (ASAP).
