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.

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.
