Hello
To Your questions:

> uml is triggering a host OS bug A host OS bug? How can I get this out from the machine?
As I wrote in a later mail, at the time the harddisk spins down, the uml kernel causes a memory error. (German: Speicherfehler) core dump.
I will try to setup a test machine which You can access to test it by Yourself, I think i can't discribe it completely enough to give You a point for a solution.
