I just compiled Xen with and I stuck on this same problem with my own compiled kernel. However the default kernel with comes from "make world" boots fine. I traced the problem down to some settings in kernel's menuconfig "Kernel hacking" menu. I dont exactly know what the option needs to be enabled in the "Kernel hacking" to get the kernel booting. In my own compiled kernels I have almost all the options in that "Kernel hacking" menu disabled, and when I enabled the same options in that menu that are in the default kernel which comes when you do "make world" the system booted fine.

You probably know the problem already but I just thought that I should share this information with you anyway.

I am afflicted by this problem for a long while now. Should look very
familiar to you. See

No solution till now.

Is it not fixed by current xen/stable-2.6.32.x kernels?
