Actually I found something very strange. Even the vanilla kernels from 
kernel.org stopped working as a domU with the transition of 2.6.32.21 to 
2.6.32.22. No output, no log, no nothing, just eating CPU time. Are 
there any debug options how to debug domUs that don't output anything?

I am actually starting to wonder if the problems are related to kernels 
at all. I tried Xen 3.4.4 with the same result. Perhaps the whole 
problem is a binutils/gcc problem. What is your version of binutils / 
gcc / glibc?
