I Have Pclos installed in /dev/sda7 of my laptop and it works great. I made this installations from a livecd a few months ago and update it to the software available at that time. Also remaster it and burned the image which i used to install another computer without problems.
Yesterday i update Pclos and more than 200 packages where updated. It still works ok on the pc and i can remaster it. But the livecd will boot and stops booting at the point it ask to choose a language. The mouse and the keyboard stop working at that point. Same thing happends if i boot a pc from this livecd as if i trie the iso to boot on vmplayer.
I case it is a problem with new kernell, i installed the oldest kernell i found on repositories as a second kernell, boot from it and remater. Same results.
My installation is 5,5gb large and the partition is 17gb so there is enought free space. Everything is installed in that partition. (no separate partition for home, boot etc).
