Running on Xen isn't the same as running the vanilla kernel!  Some options 
that you can select on vanilla Linux will certainly break things on Xen, so 
just trying the same config doesn't necessarily mean there's not a problem in 
there somewhere.

OK, so that means something's not working as it should, nobody disputes that.  
It's still not much information to go on, though.

Not all ACPI implementations are equally well-behaved.  It's possible there's 
something odd about yours.

If you try the -xen kernel config it provides a *reference point* for 
debugging your other problems: all you have to do to provide this reference 
point is build a kernel with the standard config, copy the kernel to the 
right place and try booting.

If Xen doesn't work on your machine then it means either: a) something in your 
config is producing unexpected behaviour or b) something unusual about your 
hardware is producing unexpected behaviour.

This problem doesn't happen for other people, and nobody else has your machine 
or your config, so unless you help us folks on the mailing list out in 
diagnosing what's wrong they're not going to be *able* to help you get the 
problem fixed (assuming they still want to).

Cheers,
