That is what I referred to as "particular reason". So, you have one, the 
pain is justified (:

Oh. I understood that during install something went wrong and you saw 
errors. As it's not so, forget about package manager logs.

Well, the error start to appear aster xen-qemu-dm was installed, so I 
suspect the installation of the package triggered some condition. I'm 
really curious about how it happened, but it seems that it has little to 
do with the solution.
In a neighbor branch of this thread Ian suggested that bz2 compression 
was the difference between working an broken. I would consider to 
re-build the custom kernel, making sure it's compressed in a closest to 
the default way. I think re-building the kernel is a better documented 
option, than re-compiling Xen. That way you can get a reproducible 
stable setup.

Missed that until now, sorry. Are you super-double-sure that you are 
using the same boot files on different hardware, with different results? 
md5sum can help to make file comparison.
Generally, bz2 compression is little bit more stressful for the CPU than 
gzip, but it sounds too exotic to make the difference.
