Hi,
looks like SMP in emulation mode is broken once --enable-io-thread is
turned on. Linux SMP guests lock up early during boot, often the whole
QEMU process becomes uncontrollable after a while. That's at least the
case here with x86 targets. The problem disappears when using
-enable-kvm or building without --enable-io-thread.
That's unfortunate. I've been thinking we should enable io thread by
default but this sort of regression would certainly prevent that.
Glauber/Marcelo, any guesses about what's happening?

It's not on my critical path (ie. no time to go into details), I just
stumbled over it and wanted to drop a note.
