Thank you very much for your kernel configuration file. I've tried to compile 3.3.1-gentoo with slightly modified your .config by changing CPU to Intel Core2 and disabling Xen unnecessary for Dom0 frontend drivers. And kernel seems working, but not with the app-emulation/xen. It still crashes while booting with something like: [ 1.391175] Code: 97 81 e8 5f ...
