The list is pretty the same. Thinking hard, then I used ktrace/kdump. They produced zero output, e.g. processes aren't really exist anymore - but still occupy some entries in process list. There maybe some conditions for process hanging to happen since kblankscrn was the only one found, otherwise process list should be fulfilled quite easy. >How-To-Repeat: I use KDE-3.3.0, screensaver is configured for blanking screen. Dunno if it helps to reproduce. >Fix: Sorry, no fix known. >Release-Note: >Audit-Trail: >Unformatted:
