Looks like it regressed during r20681: "(MESS) Used modern accessors for i8259."

Further testing revealed more info. In -debug, shortly after doing a vertical retrace with parameter of 1, it suddenly jumps to empty ram at 7FC3. The mystery character is 0x8A. And the hang after pressing any key is because it gets into an endless loop at F8AC.

Also, there is an overlapping io range in the address map.
