Here's what has been brought to my attention :

I've now got everything installed and confirm the kernel build
(42~14.04.1hf98078v20160516b1-Ubuntu) with sosreport and udevadm probe
succeeds on 4 affected machines.

It looks like this solves the issue.

Bug description:
  it has been brought to my attention the following:

  Kernel version: 4.2.0-30-generic #36~14.04.1-Ubuntu

  When running an sosreport on HP DL380 gen8 machines running this
  kernel (Ubuntu 14.04.4 using linux-generic-lts-wily), which includes
  hpsa 3.4.10-0, hspa causes a kernel panic when sosreport is scanning
  block devices. These are machines with an onboard p420i and
  daughtercard p420 RAID controller, with each drive in a single raid0
  configuration. (unideal, but the machines do not boot when the card is
  in HBA mode).

  This panic does not happen on kernel 3.13 with hpsa 3.4.1-0 when using
  sosreport.

  The funny thing is kernel 4.2 / 3.4.10-0 still is a more stable
  solution - I have yet to see a prior issue in which the p420 would
  lock up on this version. One issue wit h this is HP 99% of the time
  will require an sosreport when we raise any hardware issues. I can no
  longer produce that on kernel 4.2 machines because they kernel panic.

  I can reproduce this consistently with several other machines in our
  environment. - please let me know if you would like more info.
