Please boot up without Xen, the kernel that was built on Wed Sep 9 16:02:46 MSD 2009(2.6.31-rc8), and use the serial console. Using the vanilla kernel does not help me.

Attempt to bisect to rc8:- git bisect start git bisect bad fc26d1b48781ec414899947d227f533c3e3010b9 git bisect good 04106d0439e81780a48db38f5c0ee6c15a1d2f04 doesn''t allow me restore .config for Xen Dom0 support.
