It works for me on POWER8. Could you please check with the QEMU 2.10
release to see whether this is a regression or whether it was already
failing there? (Sorry, I don't have access to POWER9 anymore, so I can't
check this right now). Could you please also locate your
openbios-sparc64 file and paste it's md5sum here, so we can be sure that
it is the right version? Thanks!

PS: It's normal that you can not quit that QEMU with Ctrl-c since it has
been started without "-nodefaults" here - and that means the HMP monitor
is running multiplexed with the serial output here. To quit QEMU, you've
got to press "CTRL-a c" and then type "quit" at the monitor prompt.
