["Chenjia (C)" <chenjia09@xxxxxxxxxx>]

Dear Juergen:
           We will follow your suggestion: unload DPDK, then test a again.

        Our server have 24 vcpu, and if we press '0' it only show 10 vcpu's 
dump message,  is there a way to show more dump message?

Best Regards

The outpout seems not to be complete (its ending soemwhere in the data for vcpu 
9). Do you have the complete log?

In the log I've seen a note in the module list:

"[last unloaded: rte_dom0_mm]"

Are you using DPDK? Please be aware that there are known problems with DPDK in 
dom0 and there is no maintainer for that code. As the hang seems to be related 
to the balloon driver in dom0 I could imagine a problem in case the DPDK driver 
is doing something nasty. Please try to reproduce the problem without any DPDK 
module ever loaded since boot.
