I talked to Mingming, she suggested to use different IO scheduler. The
default scheduler is cfg, after I switch to noop, the problem is gone. 

So there seems a bug in cfg scheduler. It's easily reproduced it when
running the guest kernel, so far I haven't hit this problem on the host
side.

If I need to file a bug for some one to look at, please let me know.

Thanks
Shirley
