Oh, sorry, I didn't notice the mail... and the patch hasn't been in
qemu-xen-unstable.git tree yet.
After I applied the patch (I met with a small conflict when applying it and I

latest qemu-xen-unstable.git), looks everything backs to normal. :-)

I'm using the latest xen c/s 19696 and ioemu
72f4654095e0ac1539749b628e98f5e1569c9801 plus applying your patch manually now
and can still reproduce it.
