I tried that patch before ever posting to this list. Like I reported  
earlier, if applied I don't get a kernel panic any more but instead  
qemu crashes and is "gone". So sadly it didn't fix the issue for me  
as is.

And without knowing about interrupt controllers it is hard to fix a  
bug no-one knows what or where exactly it is and how it should be  
fixed... :(
