Hi all, 
Three days ago, the server reported lots of CMCI exceptions and Xen 3.4.2 printed hundreds of "CMCI: send CMCI to DOM0 through virq" messages to the console .  From the console output, Then I can see that Dom0 try to read the MSR_CAP regs by #GP trap in order  to log the MCA error. 

I am not sure why so many CMCI happened , maybe there were some thing wrong with the hardware.  But unfortunately the server crashed at the end. The Xen BUG ON at
    mctelem_append_processing()   
    ->  MCTE_TRANSITION_STATE(tep, COMMITTED, PROCESSING)  
    ->  BUG_ON(MCTE_STATE(tep) !=    (MCTE_F_STATE_##old)); 
  The output of the console is like this: 
(XEN) Xen bug on at mctelem.c : Line 437

Why the state of the entry is not correct ? Some one change that unexpected?  If any body even resolve this kind problems, Pls do me a favor.
