Hi David, really apologize for all the problems you mentioned here and early mails
during the reproduce. We will address them one by one ASAP to see make the reproduce
useful instead of this kind of bad experience.

BTW: if you have any patch (like debugging) to try, we are pleased to test it directly in
our testbox.

Sorry again to cost your a lot extra time for this.

Thanks
