I've merged this with my other patches and made a series with all patches
needed for AmigaOS on pegasos2 and MorphOS sound support here on branch
pegasos2-alt:
https://osdn.net/projects/qmiga/scm/git/qemu/tree/pegasos2-alt/
I hope to get it tested before Monday so we can finalise it early next
week.

Please come up with a similar workaround for this issue that I've done in
my series on which this works now without hanging. My series is on
pegasos2 branch:
https://osdn.net/projects/qmiga/scm/git/qemu/tree/pegasos2/
but I don't understand your irq mapping function and don't know how could
I add similar workaround to that.
