This patch produces the following error when booting Solaris/SPARC:

Particularly it seems that Solaris is not happy with respose length
8. Any idea, why?
The response length is not 8, it is 40; but Solaris only expected 8 (see
the CDB in the error dump).
$ sparc-softmmu/qemu-system-sparc -bios ~/ss5-170.bin -m 32 -nographic

From a quick look, it's the same bug that was reported recently on
INQUIRY commands.
If you need I can provide more input.
You can test http://article.gmane.org/gmane.comp.emulators.qemu/133434
if you have time.
