[Xen-devel] Kernel crash



Hello!

I am trying to build a custom kernel for myself that is supposed to run a 
network driver domain. To do so I configured it with the attached settings. 

Starting the kernel in a VM I get the following output using xen unstable from 
this morning:

Using config file "/etc/xen/yyyy".
Started domain yyyy, console on port 9603
