On one box everything works fine, kde4 factory installed. On this box at the same level I see the problem as "root" so far with qjackctl and VirtualBox. Doing strace, it gets to the futex line and nothing else happens.

If I run the apps as user, they work except for qjackctl which starts up and jackd shuts down, failing to connect. Thought of opening a bug, but it only happens on one box. Any ideas appreciated.
