I played with NextSTEP/sparc a few years ago and got the same impression.
I've managed to get it boot into a single user mode, but it was
unstable on disk operations. Just a simple
dd if=/dev/sd0a of=/dev/null was able to get it hanging. And I think
it was hanging in the kernel idle loop doing nothing.

If there were a Darwin/sparc ditribution, we could take a look, if
it's really a bug in NextSTEP or in qemu-system-sparc. But I couldn't
find such a distribution.
