The problem is reproducible on demand :

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Title:
kernel panic (General protection fault) on module hpsa
(lockup_detected)
Status in linux package in Ubuntu:
New
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.
