Ming,
The "-I" option of tcpdump is monitoring mode typically applicable only to wifi interfaces. So even if you run it on Thunder's NIC interfaces it will return saying that this is not supported. 

And BTW, what is eth7 ? 
>From 16.04 release all interfaces are coming up as "enP2xxxxx"

Title:
  ThunderX: soft lockup in cursor_timer_handler() Edit

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I booted a Cavium ThunderX crb1s 2.0 system using the netboot mini iso via virtual media:
    http://ports.ubuntu.com/ubuntu-ports/dists/xenial/main/installer-arm64/20101020ubuntu451/images/netboot/mini.iso

  During boot I observed the following lockup on the serial console:
