Yeah, maybe this box isn't shipped with 16.04, and its kernel is

ubuntu@arm64:~$ uname -a
Linux arm64 4.2.0 #2 SMP Mon Dec 14 04:01:19 CST 2015 aarch64 aarch64
aarch64 GNU/Linux


but the log is very similar with Dann's report:

[337056.617650] PC is at _raw_spin_unlock_irqrestore+0x30/0x40
[337056.617657] LR is at mod_timer+0x110/0x238

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:
