Make sure to use an Adeos patch >= 1.0-07. v0.9.1 ships with 1.0-02, so you
likely want to upgrade and try again. Recent Adeos patches for x86 can be found
here: http://download.gna.org/adeos/patches/v2.6/adeos/i386/

I installed the latest Fusion 9.1 patch - no changes
Do I make a mistake when I am spawning the tasks?
Second Problem ist that the uvm module has to be started twice. The first

The second attempt works!
