I just ran in to the same issue. We would get this every 3rd or 4th reboot. I simply updated everything with 'yum update" and I have not had this happen again. Also, I have seen this on my FC4 domUs, so you probably want to refresh that image as well. -Andrew Greg Brackley wrote: >I'm struggling to get Xen to boot on a FC4 Opteron box.
