RE: [Xen-devel] Re: VM hung after running sometime

Hi Jeremy:
      The test of  irqbalance disabled is running. Currently one server was crashed on NIC.
      Trace.jpg in attachments is the screenshot from serial port, and trace.txt is from /varl/log/message.
      Do you think it has connection with irqbalance disabled, or some other possibilities?
      In addition,  I find in /proc/interrupts,  all interrupts are happend on cpu0(please refer to interrputs.txt  
attached). Could it be a possible cause of server crash, and is there a way I can configure manually  to 
distribute those interrupts evenly?     
     Meanwhile,  I wil start the new test with kernel patched soon. Thanks.
