And I think I mentioned this but my other domUs, using the same xen domU 
kernel don't seem to have the issue. Well it hasn't occurred yet during 
normal use, so I could be completely off base.

Manuel, is there something i386 specific that could cause this? I have know 
idea how xen interfaces with a domU and what resources are accessed.
