Fedora xen - Jul 2006 - Error when booting with xen kernel: trap divide error

Hi,

When I boot (with the xen kernel) I get the following error messages 
which fill the whole screen and then nothing happens afterwards:

init[1] trap divide error rip:4296d7 rsp:7fffd49e7db0 error:0

I use a RAID configuration. May this cause this errors?

thanks

Oli
