Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.0 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
   BUG: unable to handle kernel paging request at 00007f4eaa03d772

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Whenever I try to run Virtualbox (vagrant) boxes on my Zbook 14 G2
  with Ubuntu 15.04, the system freezes and the only way to unlock it is
  a hard reset. I tried this with both the Ubuntu Virtualbox package
  (4.3.24-dfsg-1build1) and the commercial version
  (4.3.26-98988~Ubuntu~raring), both result in this type of crash.
