Comment #34 appears to be a *different* kernel bug again:

  watchdog: BUG: soft lockup - CPU#6 stuck for 22s! [apt-esm-hook:2930]

although what came before that is suspicious too:

  kernel: BUG: kernel NULL pointer dereference, address: 000000000000006c
  kernel: #PF: supervisor write access in kernel mode
  kernel: #PF: error_code(0x0002) - not-present page

So I would recommend trying:

 * Uninstalling VirtualBox and its kernel drivers to see if the crashes stop happening.
 * Testing the RAM overnight with https://www.memtest.org/ or https://www.memtest86.com/
