Package: xen-hypervisor-3.0.3-1-i386-pae
Version: 3.0.3-0-4
Severity: critical
Justification: breaks the whole system

Hi!

the error suddenly appeared when creating a domU
using xm create <name> on our etch server
The server freezes and isn't accessible via console/ssh anymore.
The server is a Dell PowerEdge 2900 with 2 Quad-Core Xeon E5335 and 8Gb memory.
