Can you please execute "info registers" and "x/10i $pc" from the QEMU
monitor at the time of the hang, and include the output?  Using
"-monitor stdio" or the new GTK+ interface can help.

Also, can you run under tracing (for information on how to do this, see
http://www.linux-kvm.org/page/Tracing) and include the bottom of the log?

Thanks,

Paolo
