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.
