Then if you want to use the uml machine without using the rest of

Hello,
When I do:
"date", then I wait a few seconds, then "date --set" with the
value I had in the first date, then the UML machine
takes 100% of cpu.
This occured 5 times out of 5 tries with a 2.6.25.1 kernel uml
and 2.6.22.15 host.
