Hi Brad,

I do have a vmcore + dmesg, but this is very large (total: ~16GB).

I will provide the test kernel based on Ubuntu-lts-4.2.0-36.41_14.04.1
including commit "fb53c43" and ask my contact to test it and confirm if
it mitigate the issue on their affected systems where they can reproduce
the panic on demand using the "udevadm" command.

Eric

Title:
  kernel panic (General protection fault) on module hpsa
  (lockup_detected)

Status in linux package in Ubuntu:
  Incomplete

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.
