[uml-devel] general protection failures

[Felix A. W. O. <os...@we...>]

We use UML since 4 years on one host (P4). Now we build another UML-Host
on a Xeon and all was fine. A week ago we startet the third guest at the
Xeon Host and after some time the guest was killed from the host (see
the log at the end). It is allways the third startet guest. We stopped
all guest and startet in different order and the last (third) startet
guest get the general protection error. Thanks for any help!
