[Xen-users] Xen 2.0.6 (2.6.11.10-xen0) Domain0 99% Cpu again

Hi everyone,

ive cleaned my System from any Xen resource, recompiled xen from Source again an
the CPU usage for the xend Process in Dom0 still gets to 99% after some time.
Ive attached the Trace below on during the switch to 99% Cpu on the Process.
Everything i can do after that is reboot Dom0. All other Domains are still
working *normal*
DomU Output of top during 99% CPU on Dom0

heres the trace of the xend process in Dom0. After the last
''poll'' the CPU usage
runs at 99%.

Thanks for any help
