cc'ing Richard as this was his commit. Do you have a repro case
(QEMU command line, any necessary files/images, etc) ?

I've just been trying but unfortunately do not yet have= a simple enough repro case to send. I have a custom machine which is backe= d by an fpga version of the amiga hardware. It's somewhere fairly early= in running the amiga system rom. I'll keep trying to get something sim= ple.
