Hmm, is there any way we can help with this?

Something is definitely looping.  The CPU pegs at 100%.  It does seem related 
to disk interrupts in my case. I haven't managed to make it do it anywhere 
else.  

Over the weekend I'll compile QEMU without stripping symbols and see if I can 
get gdb to help me figure out how I got into the loop.  I seem to be able to 
recreate it without any problems using Knoppix and running the knx-hdinstall 
script.  It can take a while though (15 minutes sometimes).

QEMU is amazingly good already!

Best,
Kyle
