However I can reproduce it consistently booting my OpenBIOS test images
under qemu-system-sparc:
$ ./qemu-system-sparc -cdrom debian-40r4a-sparc-netinst.iso -boot d
qemu-system-sparc: -cdrom
/home/build/src/qemu/image/sparc32/debian-40r4a-sparc-netinst.iso:
warning: bus=0,unit=2 is deprecated with this machine type

ERROR:/home/build/src/qemu/git/qemu/translate-common.c:34:tcg_handle_interrupt:
assertion failed: (qemu_mutex_iothread_locked())
