Description

When I boot sparc64/niagara (in Qemu 5.2.0 using tools/ew.py) enter kcon and run 'test *' the tests hang in mapping1.

I tried to bisect the problem with the following results:

head HANG
0.11.1 HANG
0.7.0 HANG
0.6.0 boot fails (trap to OK)
0.5.0 boot fails (trap to OK)
0.4.3 boot fails (trap to OK)
0.4.2 PASS

So this does not appear to be a new problem. I wonder if it reproduces with older/different version of Qemu as well?
